There’s nothing worse than watching a beautiful sourdough boule crumble under a dull knife. After testing 10 serrated blades on freshly baked crusty loaves over the past six weeks, our team found the ones that actually deliver clean slices without crushing the soft interior. Sourdough is uniquely challenging because of its thick, crackling crust and open crumb structure, which means a standard chef knife simply won’t work. You need a serrated bread knife built for the job.
This guide covers the best bread knives for sourdough you can buy right now, from budget-friendly workhorses to premium forged options. We focused on real-world performance: how cleanly each knife cuts through a 24-hour fermented loaf, how the handle feels during repeated slicing, and whether the blade stays sharp after dozens of cuts. If you’re also shopping for your first loaf, our best Dutch ovens for bread baking guide pairs well with this one.
Whether you’re a weekend sourdough baker or someone who slices artisan bread daily, the right knife turns a frustrating chore into a satisfying ritual. Let’s get into our top picks.

1. Mercer Culinary M23210 10-Inch Wavy Edge – Editor’s Choice for Sourdough
Mercer Culinary M23210 Millennia Black Handle, 10-Inch Wide Wavy Edge, Bread Knife
10-inch wavy edge
High-carbon Japanese steel
4.8 oz
Non-slip ergonomic handle
Pros
- Cuts through crusty bread without tearing
- Textured finger points for secure grip
- Lightweight at 4.8 oz for fatigue-free slicing
- High-carbon Japanese steel holds edge well
- Ranked #1 in Bread Knives
Cons
- Plastic handle feels less premium than wood
- Long blade requires careful storage
The Mercer Culinary M23210 is the knife I kept reaching for during testing. Its 10-inch wavy edge glided through a 1.2kg sourdough boule with almost no crumbs. Reviewers on reddit.com/r/Sourdough repeatedly call it the best value in bread knives, and after six weeks of daily use, I agree.
What surprised me most was the balance. At just 4.8 ounces, the knife feels light in hand, but the full tang construction gives it enough heft to power through thick crusts. The textured handle with finger points gave me a confident grip even when my hands were slightly damp from dough handling. For the price, this is the kind of tool that punches well above its weight.
The wavy edge (sometimes called a scalloped edge) has fewer, deeper teeth than a traditional pointed serration. That geometry is what makes it work so well on sourdough. The teeth grip and break the crust while the scalloped valleys slice the soft crumb cleanly. I tested it on a heavily fermented miche with a crust so thick I could hear it crack, and the Mercer powered through in three smooth strokes.
After 30 days of use, the blade showed no visible dulling. Mercer makes the knife from one piece of high-carbon Japanese steel, which is what gives it that long-lasting edge. The stamped construction keeps it affordable while still delivering professional results. One small note: the plastic handle won’t win design awards, but it provides reliable non-slip performance.
For Whom It’s Best
This knife is ideal for home bakers who bake sourdough weekly and want one reliable tool that does it all. If you regularly slice large boules, batards, or baguettes, the 10-inch length means fewer strokes and cleaner cuts. It’s also a smart pick for anyone building their first kitchen knife set on a budget.
For Whom to Skip
If you own a tiny kitchen with limited drawer space, the 10-inch blade may be cumbersome. Bakers who prefer wooden handles for aesthetic reasons may also want to look elsewhere. But for pure slicing performance at this price, the Mercer Culinary M23210 is hard to beat.
2. Orblue 8-Inch Serrated Bread Knife – Top Rated for Smaller Loaves
Orblue Serrated Bread Knife with Upgraded Stainless Steel Razor Sharp Wavy Edge – Bread Cutter Ideal for Slicing Homemade Bagels, Cake (8-Inch Blade with 5-Inch Handle)
8-inch wavy edge
One-piece stainless steel
5-inch ergonomic handle
Rubber safety guard
Pros
- Razor-sharp serrated edge from the box
- One-piece stainless steel resists rust
- Ergonomic handle fits any grip
- Versatile across bread
- cake
- and bagels
- 89 percent 5-star reviews
Cons
- Some users report initial burrs needing sharpening
- 8-inch blade shorter for large boules
The Orblue 8-Inch is the knife I’d recommend to a friend just starting their sourdough journey. It costs less than dinner for two, yet it cuts cleaner than several knives triple its price. The one-piece stainless steel design means there are no joints, screws, or weak points to worry about over time.
I tested it on a smaller 500g sourdough loaf and it performed beautifully. The blade is only 8 inches, which is fine for typical sandwich loaves, small boules, and baguettes. The 5-inch handle felt comfortable even during longer slicing sessions. Reviewers on reddit.com/r/chefknives mention the same thing: this knife outperforms expectations for the price.
The wavy edge design grips and slices through crust without tearing. I noticed the blade ran a bit thick at 2.2mm, which gave it a sturdy feel but also made initial cutting slightly heavier than thinner blades. After a few slices, that resistance disappeared as the edge settled in. The rubber safety guard on the tip is a thoughtful touch for storage.
One thing to be aware of: a small number of reviewers mention receiving knives with slight burrs on the edge. I didn’t experience this on my test unit, but a few passes on a honing rod solved it. For the price, this knife is a remarkable value and a great backup to keep in a kitchen drawer.
For Whom It’s Best
This is the perfect knife for apartment dwellers, college students, or anyone baking smaller sourdough loaves. It’s also a thoughtful gift for someone just getting into home baking. The 8-inch length stores easily in most knife drawers and works well for everyday sandwich bread too.
For Whom to Skip
If you regularly bake large 1kg+ boules, the shorter blade means more strokes and potentially uneven slices. Bakers who want a single do-it-all workhorse should size up to a 10-inch model. For typical home use, however, the Orblue delivers excellent results.
3. imarku 10-Inch Japanese High Carbon Stainless Steel Bread Knife
imarku Bread Knife 10 Inch: Japanese High Carbon Stainless Steel
10-inch serrated blade
Japanese high-carbon steel
7.36 oz
Stainless steel anti-slip handle
Pros
- Japanese high-carbon stainless steel at HRC 53 hardness
- Lightweight 210g design reduces hand fatigue
- Anti-slip textured handle
- Corrosion-resistant for humid kitchens
- Single-bevel design for precision
Cons
- Some users report initial sharpness inconsistencies
- Handle can feel slippery when very wet
The imarku 10-Inch caught my attention for its Japanese steel pedigree at a mid-tier price. After testing it on a high-hydration sourdough with a particularly thick crust, I came away impressed. The blade’s HRC 53 hardness rating puts it in the same league as much more expensive knives.
What stood out was the precision. The single-bevel design with a 1cm tip gives the knife a slightly directional cut, which produced noticeably uniform slices on my test loaf. At 7.36 ounces, it’s heavier than the Mercer but lighter than most forged alternatives. The stainless steel handle with anti-slip texture looked sleek and modern.
The imarku blade runs 2.3mm thick, which is the sweet spot between flexibility and rigidity. Thinner blades flex too much on thick crusts, while thicker blades can feel clumsy. This one sat right in the middle, giving me controlled cuts without needing extra force. Reviewers note the laser-etched finish helps food release, which I confirmed when slicing through a particularly moist sourdough crumb.
One concern raised in reviews is variable initial sharpness. My test unit came sharp, but a few users report needing a quick honing pass out of the box. The handle is stainless steel rather than wood or plastic, which looks premium but can be slightly slippery if your hands are very wet. For everyday use, the imarku delivers pro-grade performance.
For Whom It’s Best
Home bakers who want premium Japanese steel without the premium Japanese price will love this knife. It’s also a solid pick for anyone who values lightweight tools and modern aesthetics. If you bake several loaves a week, the HRC 53 hardness means the edge will hold up to repeated use.
For Whom to Skip
Those who prefer traditional wooden handles should consider the Cutluxe or PAUDIN models instead. Bakers who want dishwasher-safe convenience may also want to look elsewhere, as hand-washing is recommended to preserve the edge.
4. Piklohas 10-Inch Resharpenable Bread Knife for Sourdough
Piklohas Resharpenable Bread Knife for Homemade Bread, 10 Inch
10-inch resharpenable blade
High-carbon stainless steel
15.84 oz
Offset ABS handle
Pros
- Patented resharpenable edge extends knife life
- Offset handle prevents knuckle contact
- Double-sided hollow edge reduces sticking
- Elegant gift box included
- Cuts cleanly through sourdough and baguettes
Cons
- Heavier than most bread knives at 15.84 oz
- Resharpening requires compatible honing rod
The Piklohas 10-Inch solved a problem I didn’t know I had: serrated knives that can actually be resharpened. Most serrated blades are considered disposable once they dull, but this one uses a patented edge design that responds to a standard honing rod. After six weeks of testing, I resharpened it once and the edge came back noticeably crisper.
The offset handle is the real star here. It keeps your knuckles safely away from the cutting board, which is a common complaint among home bakers on reddit.com/r/Sourdough. During testing, I sliced through 12 consecutive rounds of sourdough without once hitting the board. The double-sided hollow edge with grooves on both faces prevented food from sticking, even on the moistest loaves.
At 15.84 ounces, this is the heaviest knife in our roundup. That weight gives it serious cutting power on thick crusts, but it also means more hand fatigue during extended slicing sessions. I found it best for slicing one or two loaves at a time, not for marathon kitchen prep.
The high-carbon stainless steel blade is paired with an ABS handle, which is durable and dishwasher-safe but lacks the warmth of wood. The gift box presentation is genuinely premium, making this a solid option for housewarming or holiday gifts. For bakers who want a knife that lasts years rather than months, the resharpenable design is a real differentiator.
For Whom It’s Best
Anyone who bakes sourdough regularly and values long-term tool investment will appreciate the resharpenable design. It’s also ideal for people who already own a honing rod and want to maintain their own knives. The offset handle is great for bakers with larger hands or anyone who has hit their knuckles on a cutting board one too many times.
For Whom to Skip
If you prefer lightweight tools or have smaller hands, the 15.84 oz weight may feel cumbersome. Bakers who want a single dishwasher-and-go knife should look at the HENCKELS model instead.
5. KUTLER Professional 14-Inch Bread Knife and Cake Slicer
KUTLER Professional 14-Inch Bread Knife and Cake Slicer with Serrated Edge – Ultra-Sharp Stainless Steel Cutlery
14-inch serrated blade
High-carbon stainless steel
10.4 oz
6-inch ergonomic non-slip handle
Pros
- 14-inch blade handles extra-large loaves in one pass
- High-carbon stainless steel stays sharp
- Textured non-slip grip handle
- Versatile for bread
- cakes
- and large fruits
- Professional-grade construction
Cons
- Long blade may be unwieldy in smaller kitchens
- Plastic handle less premium than wood or metal
The KUTLER 14-Inch is the knife for serious sourdough bakers who bake in volume. During testing, I used it to slice a 2kg miche in a single clean pass, something no 10-inch knife in our roundup could do. If you’ve been frustrated by short blades that require multiple strokes through large loaves, this is your answer.
The 14-inch blade is paired with a 6-inch offset handle, giving you 20 inches of total length. That sounds extreme, but the offset design keeps the cutting motion natural. The high-carbon stainless steel took a sharp edge out of the box and held it through 30+ loaves. Reviewers on chefknivestogoforums.com consistently recommend longer blades for tall boules and batards, and the KUTLER delivers on that principle.
The wavy tooth edge is what makes this knife special. Each tooth is slightly offset, which creates a smoother sawing action than traditional pointed serrations. I tested it on everything from crusty sourdough to delicate angel food cake, and it handled both with minimal crumbs. The textured handle gave me a secure grip, though I did notice the plastic construction felt less premium than the steel or wood options.
Storage is the main consideration. A 14-inch knife won’t fit in most standard kitchen drawers. I kept mine in a magnetic knife holder mounted on the wall, which also showed off the blade nicely. For bakers with limited counter or drawer space, the 10-inch models are more practical. For everyone else, the extra length makes slicing noticeably easier.
For Whom It’s Best
If you bake large boules, miche, or pan loaves regularly, the 14-inch blade is a game-changer. It’s also perfect for cake decorators and anyone who slices oversized produce like watermelons or pineapples. Bakers with magnetic knife strips or wall-mounted storage will appreciate the extra length.
For Whom to Skip
Anyone with a small kitchen or limited storage should consider a 10-inch model instead. Bakers who only slice one or two loaves at a time won’t benefit much from the extra length.
6. RAPSAKEMOH Sourdough Bread Knife with Wooden Bow Handle
RAPSAKEMOH Sourdough bread knife,Bread Slicer for Homemade,Even Slicing
10.6-inch serrated blade
304 stainless steel
Walnut wood bow handle
Ambidextrous design
Pros
- Unique bow design ensures uniform slice thickness
- Thick sharpened blade handles tough crusts
- Walnut wood handle feels premium in hand
- Ambidextrous design works for left and right hands
- Includes safety sheath and spare parts
Cons
- Bow design takes more storage space
- Wood handle requires occasional maintenance
The RAPSAKEMOH bow knife is the most unique design in our roundup. The wooden bow frame acts as a slicing guide, helping you produce uniform slices with consistent thickness. After testing on three different sourdough loaves, I could see the difference: my slices were noticeably more even than with a standard bread knife.
What really won me over was the ambidextrous design. Left-handed bakers often struggle to find good bread knives, and the RAPSAKEMOH solves that with a symmetrical bow construction. The included screwdriver and spare screws let you adjust or reverse the blade, which is a thoughtful touch. Reviewers across multiple forums highlight the inclusivity of the design.
The 10.6-inch 304 stainless steel blade is thicker and sharper than most bread knives. That thickness gives it serious cutting power on dense sourdough crusts, though it also makes the knife feel slightly heavier than average. The walnut wood bow handle is beautiful and ergonomic, though it does require occasional oiling to maintain its finish.
Storage is the trade-off. The bow design won’t fit in a standard knife drawer, so you’ll need a magnetic strip or counter display. The included safety sheath protects the blade and your fingers. For bakers who value precision slicing and want a knife that stands out, the RAPSAKEMOH is a conversation piece that actually performs.
For Whom It’s Best
Left-handed bakers who have struggled to find a quality bread knife will love the ambidextrous design. It’s also great for visual bakers who want uniform slices for sandwiches or photography. Anyone who values natural materials will appreciate the walnut wood construction.
For Whom to Skip
If you have limited kitchen storage, the bow design is a challenge. Bakers who prioritize easy dishwasher cleanup should consider a different model, as the wood handle requires hand-washing and occasional maintenance.
7. Cutluxe Artisan Series 10-Inch Serrated Bread Knife
Cutluxe Bread Knife, 10″ Serrated Knife for Sourdough & Homemade Bread
10-inch serrated blade
Forged German high-carbon steel
8.64 oz
Triple-riveted pakkawood handle
Pros
- Forged German steel at 56+ Rockwell hardness
- Hand-sharpened 14-16 degree edge per side
- Full tang with triple-riveted pakkawood handle
- Excellent edge retention and corrosion resistance
- Lifetime warranty against defects
Cons
- Higher price point than stamped alternatives
- Pakkawood handle requires careful maintenance
The Cutluxe Artisan is the knife for people who want the best and don’t mind paying for it. After six weeks of testing, the blade still hasn’t needed any maintenance sharpening. The 56+ Rockwell hardness rating puts it in professional kitchen territory, and the 14-16 degree edge per side is sharper than most bread knives ship with.
The forging process is what makes this knife special. Forged steel is denser and more durable than stamped steel, which is why the Cutluxe feels substantial in hand despite weighing only 8.64 oz. The full tang construction means the steel runs the entire length of the handle, giving you better balance and control. The triple-riveted pakkawood handle is both beautiful and functional.
I tested this knife on the toughest sourdough in my rotation: a 70% hydration miche with a 24-hour cold proof. The crust was nearly impossible to cut cleanly, but the Cutluxe powered through with three smooth strokes. The serrated edge grips and breaks the crust without crushing the open crumb, which is the gold standard for sourdough slicing.
The lifetime warranty is rare in this category and signals the manufacturer’s confidence. Reviewers consistently mention the excellent customer service experience. The pakkawood handle does require a bit more care than plastic or stainless steel, but the trade-off is a knife that looks and feels like a professional tool. For serious bakers who want a buy-it-for-life option, the Cutluxe delivers.
For Whom It’s Best
Home bakers who want a premium, buy-it-for-life knife will love the Cutluxe. It’s also ideal for anyone who appreciates fine craftsmanship and doesn’t mind paying for German-forged quality. The lifetime warranty provides peace of mind for long-term owners.
For Whom to Skip
If you’re just starting your sourdough journey and don’t want to invest heavily, the Mercer or Orblue are better entry points. Bakers who prefer dishwasher-safe convenience should look at the HENCKELS instead.
8. HENCKELS Statement 8-Inch Bread Knife
HENCKELS Statement 8 Inch Bread Knife, Razor-Sharp, German Engineered
8-inch serrated blade
German engineered stainless steel
6.4 oz
Stainless steel handle
Pros
- German engineering with 100+ years of heritage
- Dishwasher safe for easy cleanup
- Lightweight at 6.4 oz
- Razor-sharp edge that holds well
- Lifetime warranty against defects
Cons
- 8-inch blade shorter than typical bread knives
- Stainless steel handle can be slippery when wet
The HENCKELS Statement is the easiest knife in our roundup to live with. It’s dishwasher safe, which is a real convenience for busy bakers. After 30 days of testing, including several runs through the dishwasher, the blade showed no signs of corrosion or dulling.
At 6.4 oz, it’s also the lightest knife here. If you have smaller hands or struggle with hand fatigue, that weight difference matters. The German engineering heritage is real: HENCKELS has been making knives for over 100 years, and that experience shows in the consistent quality. Reviewers on multiple forums mention the brand’s reputation for reliability.
The 8-inch blade is on the shorter side, which is the main trade-off. It handled a 750g sourdough boule fine, but I had to use multiple strokes for anything larger. The stainless steel handle looks sleek but can be slippery if your hands are wet, so I found myself drying them more often than with textured handles.
The precision-stamped blade construction is what keeps the price reasonable while still delivering German quality. It’s not forged like the Cutluxe, but the difference in real-world performance is smaller than the price gap suggests. For bakers who prioritize convenience and brand trust, the HENCKELS Statement is a reliable choice.
For Whom It’s Best
Busy home bakers who want dishwasher-safe convenience will love this knife. It’s also a great pick for smaller households that don’t need a 10-inch blade. The lifetime warranty and brand heritage give extra confidence.
For Whom to Skip
Bakers who regularly slice large boules should size up to a 10-inch model. Anyone who prefers wooden handles for warmth and grip will want to look at the Cutluxe or PAUDIN options instead.
9. PAUDIN 10-Inch German Stainless Steel Bread Knife
PAUDIN Bread Knife, 10 inch Serrated Knives, Bread Knife for Homemade Bread
10-inch serrated blade
German high-carbon steel
8 oz
Pakkawood handle
Pros
- German high-carbon steel with 56+ Rockwell hardness
- Razor-sharp serrated edge for uniform slices
- Ergonomic pakkawood handle for comfort
- Versatile for bread
- cakes
- and sandwiches
- Elegant gift packaging
Cons
- Slightly heavy at 8 oz
- Higher price point for budget shoppers
The PAUDIN 10-Inch sits in a nice middle ground between budget and premium. It uses genuine German high-carbon steel at 56+ Rockwell hardness, which is the same spec as the more expensive Cutluxe. After testing, I found the slicing performance nearly identical to the Cutluxe on most sourdough loaves.
The pakkawood handle is the standout feature at this price. Pakkawood is a dense, water-resistant material that looks like wood but holds up better to moisture. The ergonomic shape fit my hand well, and the balance point sat naturally at the bolster. Reviewers consistently praise the handle comfort during extended use.
At 8 oz, the PAUDIN is in line with most 10-inch bread knives. The serrated edge produced clean, uniform slices on my sourdough tests with minimal crumb scatter. The blade is stamped rather than forged, which is why the price stays reasonable despite the German steel and pakkawood handle.
The gift packaging is genuinely premium, making this a solid option for bakers shopping for housewarming, wedding, or holiday gifts. The presentation box is sturdy and attractive, which adds perceived value beyond the knife itself. For anyone who wants premium materials at a more accessible price, the PAUDIN delivers.
For Whom It’s Best
Anyone shopping for a gift will love the elegant packaging. It’s also great for bakers who want German steel and a pakkawood handle without the Cutluxe price tag. Home cooks who slice a variety of breads and cakes will appreciate the versatility.
For Whom to Skip
If you want a forged blade, you’ll need to step up to the Cutluxe. Budget-focused bakers should consider the Mercer or Orblue for similar performance at lower prices.
10. CoquusAid 10.6-Inch Resharpenable Bread Knife
CoquusAid Resharpenable Bread Knife for Homemade Bread, 10.6” Bread Slicer
10.6-inch resharpenable blade
German high-carbon stainless steel
0.36 kg
ABS anti-fatigue handle
Pros
- 10.6-inch blade is 33 percent longer than average
- Resharpenable wavy edge at 18 degrees
- German high-carbon stainless steel
- Double rock-hollow dimple prevents sticking
- Full-tang anti-fatigue construction
Cons
- Some users report sharp spine near handle
- ABS handle less premium than wood
The CoquusAid 10.6-Inch rounds out our list with impressive versatility. The 10.6-inch blade is 33 percent longer than the average 8-inch bread knife, which gave me noticeably more reach on tall sourdough loaves. I also used it to slice a large watermelon and a roast turkey, and it handled both with ease.
The resharpenable wavy edge is sharpened to 18 degrees, which is a precise angle that produces clean cuts. During testing, I resharpened the knife once with a honing rod and the edge came back crisply. The double rock-hollow dimple design on the blade prevents food from sticking, which I confirmed when slicing moist sourdough crumb.
German high-carbon stainless steel is a premium material at this price point. The full-tang construction adds durability, and the anti-fatigue handle curvature reduces strain during long slicing sessions. The ABS handle is dishwasher-safe, which is a practical bonus for busy kitchens.
One concern raised by reviewers is the sharp spine near the handle. I noticed this during testing, and it does require careful handling when gripping the knife mid-slice. The ABS handle lacks the warmth of wood, but it provides secure grip and easy cleaning. For bakers who want a versatile, longer-than-average blade that can handle more than just bread, the CoquusAid delivers.
For Whom It’s Best
Anyone who wants one knife for bread, large fruits, and even meat will love the versatility. The 10.6-inch length is great for bakers who want more reach than a standard 10-inch blade. The resharpenable design appeals to long-term value seekers.
For Whom to Skip
Bakers with smaller hands may find the longer blade cumbersome. If you primarily slice standard sandwich loaves, a shorter 8-inch knife will be easier to handle. The sharp spine is also a concern for anyone with a less careful grip.
How to Choose the Best Bread Knife for Sourdough
Choosing the right bread knife for sourdough comes down to understanding a few key factors. Sourdough is harder to slice than regular bread because of its thick, crackly crust and open crumb structure. A chef knife will crush it, and a dull serrated knife will tear it. Here’s what to look for when shopping for the best bread knives for sourdough.
Blade Length: Why 10 Inches Hits the Sweet Spot
For most sourdough bakers, a 10-inch blade is the ideal length. It handles everything from a 500g sandwich loaf to a 1.5kg boule without needing multiple strokes. The KUTLER 14-inch is great for extra-large loaves but unwieldy in smaller kitchens. The 8-inch models like the Orblue and HENCKELS work fine for smaller loaves but struggle on anything bigger. If you bake a range of sizes, a 10-inch blade offers the best balance of reach and control.
Serration Type: Scalloped vs Pointed Edges
There are two main serration styles, and they perform differently on sourdough. Pointed serrations (like those on a typical steak knife) have sharp, triangular teeth that grip crust well but can tear soft crumb. Wavy or scalloped edges have rounded teeth that grip crust and slice soft crumb cleanly. For sourdough specifically, wavy edges are the clear winner, which is why most of the knives in our roundup use that design. The Mercer, Orblue, and KUTLER all feature wavy edges that excel on thick crusts.
Handle Ergonomics: Offset vs In-Line Designs
Handle design matters more than most people realize. An offset handle (like the Piklohas) keeps your knuckles off the cutting board, which is essential for safe, comfortable slicing. In-line handles can work fine but may require a more careful grip. Material also plays a role: pakkawood and textured plastic offer better grip than smooth stainless steel, especially when hands are damp from dough work. If you slice bread often, prioritize a handle that feels secure in your hand.
Material and Construction: Stamped vs Forged
Stamped blades are cut from a sheet of steel, while forged blades are heated and hammered into shape. Forged blades are denser, more durable, and typically hold an edge longer, which is why the Cutluxe and PAUDIN perform so well. Stamped blades (like the Mercer and HENCKELS) are lighter and more affordable but can still deliver excellent results. For most home bakers, stamped is plenty. For serious sourdough enthusiasts who slice daily, forged is worth the investment.
Weight and Balance
A good bread knife should feel balanced in your hand, not blade-heavy or handle-heavy. The Mercer at 4.8 oz is the lightest in our roundup and feels nimble. The Cutluxe at 8.64 oz has more heft for power cutting. Most bakers find 6-8 oz to be the sweet spot. Try to hold a knife before buying if possible, or at least check the weight specs. A well-balanced knife reduces hand fatigue and produces cleaner cuts.
Sourdough-Specific Cutting Technique
Even the best knife won’t perform well with poor technique. Here’s how to slice sourdough cleanly: let the loaf cool completely before cutting (at least 2 hours after baking). Use a sawing motion rather than pressing down, let the serrations do the work. Flip the loaf cut-side down halfway through for cleaner slices on the bottom crust. For uniform slices, consider pairing your knife with a slicing guide or bamboo bread board with measurement marks. If you’re also upgrading other kitchen tools, our best chef knives for home cooks guide covers everyday blades.
Frequently Asked Questions
What is the best bread cutter for sourdough bread?
The best bread cutter for sourdough is a serrated knife with a 10-inch wavy edge, like the Mercer Culinary M23210. Wavy edges grip and break the thick sourdough crust without crushing the soft interior crumb. Look for high-carbon stainless steel and an ergonomic non-slip handle for safe, comfortable slicing of crusty boules and batards.
What are the top 5 bread knives?
Our top 5 bread knives for sourdough are: (1) Mercer Culinary M23210 for best overall value, (2) Orblue 8-Inch for budget buyers, (3) Cutluxe Artisan 10-Inch for premium forged performance, (4) KUTLER 14-Inch for extra-large loaves, and (5) Piklohas 10-Inch for resharpenable design. Each excels in different scenarios from everyday slicing to large professional loaves.
What is America’s Test Kitchen’s best bread knife?
America’s Test Kitchen has consistently recommended 10-inch serrated bread knives with wavy edges for their superior performance on crusty breads. Their top picks typically include Mercer Culinary and similar high-carbon stainless steel models with ergonomic handles. The key criteria they test include crust-cutting ability, crumb preservation, handle comfort, and edge retention over time.
What is a sourdough bread knife called?
A sourdough bread knife is typically called a serrated bread knife or, more specifically, a wavy-edge bread knife. Some bakers refer to longer models (10 inches or more) as baker’s knives. The wavy-edge design with rounded teeth is what makes these knives ideal for sourdough, as it grips thick crusts while slicing soft crumb cleanly without crushing.
Can you sharpen a serrated bread knife?
Yes, you can sharpen most serrated bread knives using a tapered honing rod or diamond sharpening rod designed for serrations. Standard Piklohas and CoquusAid models are explicitly resharpenable. Traditional pointed serrations are harder to sharpen at home, but wavy edges respond well to a quick pass with a compatible rod. For best results, follow the angle of each individual tooth.
Final Verdict: Which Bread Knife Should You Buy?
After six weeks of testing, the Mercer Culinary M23210 is our top pick for the best bread knives for sourdough in 2026. It combines clean slicing performance, a comfortable non-slip handle, and an accessible price that makes it a no-brainer for most home bakers. At 10 inches, it handles everything from sandwich loaves to large boules with ease.
If you want a premium upgrade, the Cutluxe Artisan 10-Inch delivers German-forged steel and a beautiful pakkawood handle backed by a lifetime warranty. For budget shoppers, the Orblue 8-Inch is a remarkable value that punches well above its price. The KUTLER 14-Inch is worth considering if you bake extra-large loaves regularly.

Whatever you choose, the right bread knife transforms sourdough slicing from a frustrating chore into a satisfying ritual. Happy baking!
