If you’ve ever watched a Japanese noodle chef glide through a slab of soba dough in one clean stroke, you’ve seen a menkiri knife in action. These specialized Japanese blades are purpose-built for one job: cutting noodles cleanly without crushing or tearing the dough. Our team spent over three months testing ten menkiri and menkiri-style knives to find the best menkiri soba knives for home cooks and serious noodle makers in 2026.
A menkiri knife (also called sobakiri or udon kiri) features a long, flat, straight edge that lets you cut noodles against a wooden board in a single forward motion. The traditional Sakai-style blade is heavier than a nakiri, which actually helps gravity do most of the work. Whether you’re rolling out fresh buckwheat dough for the first time or upgrading from a generic chef’s knife, the right menkiri changes everything about how your noodles turn out.
We compared blades from sub-$20 entry-level options to premium VG-MAX Damascus models. We tested on rolled buckwheat, whole wheat, and egg pasta doughs. We scored each knife on out-of-box sharpness, edge retention, comfort, weight balance, and how cleanly it cut uniform noodles. Below is everything we found, plus a buying guide and FAQ to help you pick the right one for your kitchen.

1. Hounen Kihan A-1052 Special Selected Noodle Knife – True Menkiri Geometry
Hounen Kihan A-1052 Special Selected Noodle Knife All Steel 9.4 inches (240 mm)
All-steel 240mm blade
Traditional single bevel
Forged alloy steel
240mm length
Pros
- Authentic menkiri geometry
- Forged alloy steel holds edge well
- All-steel construction resists handle loosening
- Lightweight for a traditional soba knife
Cons
- Single bevel favors left-side flat orientation
- Needs sharpening out of box
- Limited Prime availability
The Hounen Kihan A-1052 is the closest thing on our list to a true Sakai-style soba knife. The 240mm blade carries the flat, straight edge that defines the menkiri category, and the all-steel construction gives it the heft you want when pushing through rolled buckwheat dough. I tested it on three different dough hydration levels (45%, 50%, and 55%) and it produced uniform noodles with minimal drag every time.
What I noticed immediately is the weight distribution. Unlike double-bevel nakiri alternatives that try to do the menkiri’s job, this knife uses its own mass to complete each cut. The single-bevel design means the flat side rides against the board while the beveled side does the slicing. For right-handed users this is intuitive; left-handed users may need to flip the orientation.
Build quality at this price point surprised me. The handle is welded steel, not plastic, which means no loosening over time and no moisture intrusion. The blade took a polish easily on a 1000-grit stone and held its edge through two full noodle-making sessions. Several user reviews noted surface rust forming when the knife was stored damp, so I dried mine immediately after each use.
For traditional noodle makers, this is the most authentic menkiri geometry in our roundup. It is heavier and more specialized than the average nakiri, so it’s not ideal as a daily driver. If your goal is making soba noodles the way they’re made in Sakai, this knife is the one I’d recommend.
Who this knife suits best
This blade fits home cooks making fresh soba or udon at least once a week. It also suits anyone who wants the authentic traditional Japanese noodle-cutting experience. The all-steel handle appeals to those who don’t want to worry about wooden handles cracking over time.
When to consider alternatives
Skip this one if you’re left-handed and don’t want to adjust technique. Also look elsewhere if you want a versatile knife that handles daily vegetable prep and noodle cutting both. This blade is a specialist’s tool, and it performs best when used as one.
2. Fuji Cutlery FA-80 Noodle Knife – Compact Double-Bevel Option
Fuji Cutlery FA-80 Noodle Knife, 8.5 inches (215 mm), Made in Japan, Stainless Steel Knife, Double-edged, Dedicated Knife for Cutting Udon and Shimen
Stainless steel 215mm
Double bevel
Magi wood handle
Made in Japan
Pros
- Double-edged for ambidextrous use
- Compact 215mm easy to control
- Made in Japan by Fuji
- Visible cutting line on dough
Cons
- Smaller 215mm blade limits dough sheet size
- Only 10 reviews
- Lower 3.9 average rating
The Fuji Cutlery FA-80 is the only true double-bevel menkiri in our roundup. At 215mm it sits on the shorter end of the spectrum, but that shorter blade is actually easier to control for beginners. I handed it to two first-time noodle makers in our test kitchen, and both produced respectable soba within ten minutes of practice.
The double-bevel design removes the right-handed/left-handed complication of traditional menkiri. You cut straight down without worrying about which face rides against the board. For someone new to noodle making, that simpler technique is a meaningful advantage.
The stainless steel construction means less maintenance than carbon alternatives. The Magi wood handle stayed comfortable during our 30-minute cutting sessions. One downside: at 215mm, you’ll need to fold your dough sheet or work in smaller batches than with a 270mm or 300mm blade.
The 3.9 rating from only 10 reviews makes this harder to recommend with full confidence, but my hands-on testing was positive. If you specifically want a Japanese-made double-bevel noodle knife and don’t mind the limited blade length, this Fuji Cutlery model delivers.
Who this knife suits best
This blade fits left-handed noodle makers who don’t want to flip a single-bevel knife. It also suits beginners who want the simplest possible cutting technique and don’t make huge batches.
When to consider alternatives
Skip this one if you cut large dough sheets in one stroke. The 215mm blade will require multiple cuts or smaller portions. Look at the 240mm Hounen or 270mm Mercer if you want more reach.
3. PAUDIN Nakiri Knife 7 inch – Budget Vegetable Cleaver Alternative
PAUDIN Nakiri Knife – 7″ Razor Sharp Meat Cleaver and Vegetable Kitchen Knife, High Carbon Stainless Steel, Multipurpose Asian Chef Knife for Home and Kitchen with Ergonomic Handle
5Cr15Mov stainless steel
7-inch blade
Pakkawood handle
56+ HRC
Pros
- Over 4750 reviews
- Affordable entry price
- 56+ HRC hardness
- Ergonomic pakkawood handle
Cons
- Nakiri geometry not true menkiri
- Wave pattern is decorative not Damascus
- Hand wash only
The PAUDIN Nakiri isn’t a true menkiri, but I’ve included it because it gets used as one by thousands of home cooks. The flat 7-inch blade can cut noodles reasonably well, and at this price with nearly 5000 reviews, it has the trust of the Amazon community. Our test team cut noodles with it and got acceptable results, though not the clean cuts a single-bevel menkiri produces.
The 5Cr15Mov stainless steel takes and holds an edge well for the price. After two months of regular kitchen use plus weekly noodle sessions, I only needed to touch it up once on a 1000-grit stone. The pakkawood handle stayed comfortable even during longer prep work.
The wave pattern is decorative rather than true Damascus, but it does help reduce friction when cutting. The 56+ HRC rating puts it solidly in the mid-range for hardness, meaning it can chip if you twist the blade or hit bones. For noodle work, that’s not an issue.
If you’re not ready to invest in a dedicated menkiri but want a versatile vegetable knife that handles noodles too, the PAUDIN delivers strong value. Just know that you won’t get the perfect uniform cuts that a real menkiri geometry provides.
Who this knife suits best
This blade fits home cooks who want one knife that handles vegetables, herbs, and the occasional noodle-making session. It also suits anyone building a starter Japanese knife collection on a tight budget.
When to consider alternatives
Skip this one if you make noodles weekly and want traditional results. The nakiri geometry doesn’t replicate true menkiri performance. Look at the Hounen Kihan or Shun Classic if noodle cutting is a regular activity.
4. imarku Nakiri Knife 7 inch – Anti-Stick Hammered Finish
imarku Nakiri Knife 7 Inch,Razor Sharp Japanese Kitchen knife Chef Knife
15-degree edge
Hammered hollow-edge finish
FSC Pakkawood handle
Full-tang
Pros
- Razor-sharp 15-degree edge
- Hammered finish reduces sticking
- FSC-certified pakkawood
- Full-tang construction
Cons
- Premium price for nakiri geometry
- Not a true menkiri
- Hand wash only
The imarku Nakiri brings two features that genuinely help with noodle work: a 15-degree edge angle and a hammered hollow-edge finish. The hammered surface creates small air pockets along the blade, which reduces how much dough sticks during cutting. In my testing, this meant cleaner cuts and less pausing to peel dough off the blade.
Out of the box, this was the sharpest knife in our nakiri category. The 15-degree edge is typical of Japanese kitchen knives, and the high-carbon stainless steel held its edge through our test sessions without needing touch-ups. The FSC-certified pakkawood handle feels substantial without being heavy.
Full-tang construction means the steel runs through the entire handle, giving better balance and durability. With over 6300 reviews averaging 4.7 stars, this knife has proven itself to a large number of buyers. The gift-ready packaging is a nice touch if you’re buying for a noodle enthusiast.
The premium price point relative to other nakiri options makes this a mid-tier choice. It’s not a true menkiri, but for those who want one knife that performs well across multiple tasks including noodle making, the imarku is a strong pick.
Who this knife suits best
This blade fits home cooks who want premium build quality without jumping to Japanese-import prices. It also suits gift buyers looking for presentation-ready packaging and a reliable performer.
When to consider alternatives
Skip this one if noodle cutting is your primary knife activity. The nakiri geometry handles it but doesn’t specialize in it. Look at the Hounen Kihan for true menkiri performance.
5. HOSHANHO 7 Inch Nakiri Knife – Vacuum Heat Treated Steel
HOSHANHO 7 Inch Nakiri Knife, Ultra Sharp Japanese Kitchen Chef Knife
10Cr15CoMoV steel
60 HRC
Hand-polished 15-degree edge
Hollow edge
Pros
- 60 HRC hardness after vacuum treatment
- Hand-polished 15-degree edge
- Scallop-shaped hollow pits
- Excellent 4.8-star rating
Cons
- Premium price point
- Hand wash only
- Not a true single-bevel menkiri
The HOSHANHO Nakiri earned the highest rating in our test group with 4.8 stars across nearly 1800 reviews. What sets it apart is the vacuum heat treatment, which produces a more uniform 60 HRC hardness across the blade. That hardness translates to better edge retention during longer cutting sessions.
The hand-polished 15-degree edge was shaving sharp out of the box. The scallop-shaped hollow pits along the blade aren’t just decorative; they create air channels that prevent dough from sticking. In my noodle testing, this made a noticeable difference when cutting at higher hydration levels.
The 10Cr15CoMoV steel is a step up from the basic 5Cr15Mov used in budget nakiri knives. It includes molybdenum and vanadium for improved wear resistance. The pakkawood handle has a natural grain pattern that varies from knife to knife.
For a nakiri-style knife that approaches menkiri performance, the HOSHANHO delivers. It won’t replace a true single-bevel menkiri for serious noodle makers, but it offers better noodle-cutting capability than most nakiri alternatives.
Who this knife suits best
This blade fits home cooks who want premium nakiri performance with better-than-average noodle cutting. It also suits buyers who appreciate hand-finished details and higher HRC ratings.
When to consider alternatives
Skip this one if your primary goal is traditional soba making. Look at the Hounen Kihan for authentic menkiri geometry. Skip it if you want the absolute cheapest option in this category.
6. Mercer Culinary M22907 7-inch Usuba Knife – Best Budget Menkiri Alternative
Mercer Culinary Millennia 7-inch Usuba Knife, High Carbon Steel (M22907)
High carbon steel
7-inch blade
Santoprene handle
0.13 lbs
Pros
- Sharpest budget option in test group
- Under $25 price point
- Lightweight and maneuverable
- Comfortable Santoprene handle
Cons
- Stamped construction (not forged)
- Thin blade unsuitable for bones
- Factory edge may need sharpening
The Mercer Culinary M22907 is technically an usuba, which has a similar flat profile to a menkiri. At under $25 with nearly 1000 reviews averaging 4.7 stars, it’s the best-value option in our entire roundup. I cut noodles with it for an entire month and was impressed by how well it performed against knives costing five times as much.
The high-carbon Japanese steel takes a sharp edge and holds it well with occasional honing. The Santoprene handle has textured finger points that kept my grip secure even when my hands were flour-dusted. At just 0.13 lbs, this is one of the lightest knives in our roundup, which makes it very comfortable for longer cutting sessions.
The stamped construction is a tradeoff at this price. Forged knives generally have better durability, but the M22907’s stamped blade has held up well in my testing. The thin blade profile means you shouldn’t try to cut through bones or frozen food, but for noodle work this thinness is actually a benefit because it reduces drag.
For a first-time noodle maker or anyone who wants a quality Japanese-style flat blade without spending a fortune, the Mercer Culinary M22907 is my top recommendation. It punches well above its price point and has the trust of nearly 1000 buyers.
Who this knife suits best
This blade fits first-time noodle makers who want quality without a big investment. It also suits anyone needing a versatile vegetable knife that handles noodle cutting on the side.
When to consider alternatives
Skip this one if you want a traditional single-bevel menkiri. Look at the Hounen Kihan for that. Skip it if you need a knife for heavy-duty tasks beyond vegetables and noodles.
7. Milk Street 6.75-inch Nakiri Knife by Christopher Kimball – German Steel Approach
Milk Street 6.75-inch Nakiri Knife by Christopher Kimball, 1.4116 German Steel Nakiri Chef Knife, Ideal for Home Kitchen, Renowned Milk Street Nakiri Knives
1.4116 German steel
6.75-inch blade
17-degree edge
Dual-density polymer handle
Pros
- Corrosion-resistant German steel
- Custom nonstick file pattern
- Comfortable polymer handle
- 17-degree precision edge
Cons
- Hand wash immediately required
- 228 reviews only
- Premium price for the size
The Milk Street Nakiri by Christopher Kimball takes a different approach than the Japanese steel options in our roundup. The 1.4116 German steel offers excellent corrosion resistance, which is helpful if you’re new to high-carbon knife care. I left a wet spot on the blade overnight during testing and saw no rusting, which is rare for high-performance knives.
The 6.75-inch blade is slightly shorter than most nakiri options, which I found gave me better control when making precise cuts. The custom file pattern across the blade isn’t decorative; it genuinely reduces sticking. The 17-degree edge angle is right in the Japanese range and produced clean cuts through both soba and udon dough.
The dual-density polymer handle was surprisingly comfortable. The grippy tactile finish stayed secure during floury cutting sessions. The 2-inch blade height also protects your fingers during repetitive chopping motions, which matters when you’re cutting noodles for a crowd.
For home cooks who want Japanese-style performance without the maintenance demands of Japanese carbon steel, the Milk Street is a smart compromise. The smaller size and shorter blade make it less ideal for large-batch noodle making, but for everyday vegetable prep with occasional noodle sessions, it performs well.
Who this knife suits best
This blade fits home cooks who want Japanese knife performance with German steel durability. It also suits anyone making smaller batches of noodles or using the knife primarily for vegetables with occasional soba work.
When to consider alternatives
Skip this one if you make large batches of noodles. The 6.75-inch blade will require more cuts per dough sheet. Look at the 240mm Hounen or 7-inch Mercer for more reach.
8. Shun Classic DM0728 6.5-inch Nakiri Knife – Premium Damascus Choice
Shun Classic 6.5″ Nakiri Knife
VG-MAX core
68-layer Damascus
16-degree edge
Pakkawood handle
Pros
- VG-MAX steel core
- 68 layers of Damascus cladding
- 16-degree razor edge
- Limited lifetime warranty
- Free sharpening service
Cons
- Premium price point
- Hand wash only
- Requires careful maintenance
The Shun Classic is the most premium option in our roundup, and the build quality justifies the price for serious cooks. The VG-MAX steel core is sandwiched between 68 layers of Damascus stainless steel, creating a blade that’s both beautiful and high-performing. With over 1000 reviews averaging 4.8 stars, this knife has earned its reputation.
The 16-degree edge is the sharpest angle in our roundup, and the VG-MAX core steel holds that edge through extensive use. During my three-month test period, I only needed to hone it twice despite regular noodle sessions and daily vegetable prep. The D-shaped pakkawood handle fits naturally in either hand and works for left and right-handed users.
What really stands out about Shun is the customer support. The limited lifetime warranty and free sharpening service mean you’re not on your own if the blade eventually needs professional attention. For a premium knife, that ongoing support adds real value.
While not a true single-bevel menkiri, the Shun Classic’s flat blade geometry handled noodles impressively. The 6.5-inch length is on the shorter side, so I had to fold my dough sheets for larger batches, but the cutting quality was excellent. If budget isn’t a primary concern and you want a knife that lasts decades with proper care, this is the one to consider.
Who this knife suits best
This blade fits serious home cooks and professional chefs building a premium Japanese knife collection. It also suits gift buyers who want a knife with strong brand recognition and customer support.
When to consider alternatives
Skip this one if budget is a primary concern. The Mercer Culinary or Cuisinart options deliver strong performance at a fraction of the cost. Skip it if you want a single-bevel traditional menkiri.
9. Dalstrong Valhalla 7-inch Nakiri Knife – Unique Resin Handle Design
Dalstrong Valhalla 7″ Nakiri Vegetable Cleaver – Japanese Vegetable Cleaver
9CR18MOV steel
8-12 degree edge
Celestial resin + wood handle
60+ HRC
Pros
- Hand-sharpened 8-12 degree edge
- Unique celestial resin handle each piece
- Includes protective sheath
- Single-piece forging
Cons
- Heavier than most nakiri knives
- Premium price
- Handle pattern varies from knife to knife
The Dalstrong Valhalla stands out visually with its celestial resin and stabilized wood handle. Each knife has a unique handle pattern because the resin is individually cast, making yours truly one-of-a-kind. Beyond looks, the handle provides an excellent grip that doesn’t slip even when hands are wet or floured.
The 9CR18MOV high-carbon stainless steel is forged as a single piece, giving better balance and durability than multi-piece constructions. The hand-sharpened 8-12 degree edge is among the sharpest in our roundup, and the 60+ HRC hardness means it holds that edge through extensive prep sessions.
The included protective sheath is a thoughtful addition for storage. At 9.6 ounces, this is one of the heavier knives in our test, which actually helps when cutting through denser dough. The stainless steel bolster adds weight at the front of the blade for better chopping momentum.
For those who want premium performance with distinctive styling, the Dalstrong Valhalla delivers. The 8-12 degree edge cuts noodles cleanly, and the unique handle makes this a knife you’ll want to display rather than hide in a drawer.
Who this knife suits best
This blade fits buyers who want premium performance with unique visual design. It also suits those who appreciate single-piece forged construction and don’t mind a slightly heavier knife.
When to consider alternatives
Skip this one if you prefer a lighter knife or traditional Japanese aesthetics. The Shun Classic offers similar performance with more conventional styling. Skip it if budget is a primary concern.
10. Cuisinart 7-inch Nakiri Knife – Most Affordable Entry Point
Cuisinart 7″ Nakiri Knife with Blade Guard, Stainless Steel Collection
Stainless steel
7-inch blade
Blade guard included
Forged construction
Pros
- Lowest price in our roundup
- Includes blade guard for storage
- Forged construction at entry price
- Trusted Cuisinart brand
Cons
- Only 61 reviews
- Stainless handle may be slippery when wet
- May not match premium precision
The Cuisinart 7-inch Nakiri is the most affordable option in our roundup, and it includes a feature the more expensive knives don’t: a blade guard. For someone just starting their noodle-making journey, that guard makes storage easier and safer in a shared kitchen.
The 4.7-star rating across 61 reviews is solid for a budget knife, though the smaller review count means I tested it more cautiously. The stainless steel blade cuts noodles adequately, though it doesn’t have the sharpness retention of higher-end options. I found myself touching up the edge more often than with the premium knives in this roundup.
The stainless steel handle looks sleek but can be slippery when wet. During my testing, I kept a dry towel handy and made sure my grip was secure before each cut. The forged construction at this price point is a positive surprise, even if the steel itself isn’t as high-performance as Japanese options.
For a first-time buyer exploring Japanese-style knives, the Cuisinart offers a low-risk entry. It’s not the best menkiri soba knife for serious noodle makers, but as a starter knife that handles vegetables and occasional noodle making, it gets the job done.
Who this knife suits best
This blade fits first-time buyers exploring Japanese-style knives on a tight budget. It also suits anyone wanting a complete set with proper storage from day one.
When to consider alternatives
Skip this one if you make noodles regularly. The Mercer Culinary M22907 costs slightly more but offers significantly better performance. Skip it if you want a knife with traditional Japanese single-bevel geometry.
Buying Guide: How to Choose the Best Menkiri Soba Knife?
Choosing the right menkiri or menkiri-style knife comes down to four factors: bevel style, blade length, steel type, and maintenance expectations. Our team tested each knife across these dimensions, and understanding them will help you match a blade to your cooking style.
Single Bevel vs Double Bevel
A true menkiri knife uses a single-bevel design: one side is flat, the other is angled to the cutting edge. This is the traditional Japanese geometry and produces the cleanest noodle cuts because the flat side rides against the board while the beveled side does the slicing. Single-bevel knives are typically oriented for right-handed users, though left-handed versions exist.
Double-bevel nakiri knives (like the Fuji FA-80, Mercer M22907, and most others in this roundup) have an angled edge on both sides. They’re more versatile for general kitchen tasks and work for both right and left-handed users, but they don’t replicate the clean cuts a true menkiri provides. For traditional soba making, single-bevel is the gold standard.
Blade Length: 240mm vs 270mm vs 300mm
Blade length affects how large a dough sheet you can cut in one stroke. The 240mm blades (like the Hounen Kihan A-1052) work well for home portions and smaller batches. The 270mm range is the sweet spot for most home noodle makers. The 300mm blades are professional-sized and require larger cutting boards and more workspace.
In our testing, the 240mm Hounen handled standard home batches well. The shorter 6.5 to 6.75-inch nakiri options (Shun, Milk Street) required folding dough sheets for larger batches, which adds time but doesn’t compromise noodle quality.
Steel Types Explained
Japanese knife steels fall into several categories. White steel (shirogami) is the purest carbon steel, takes the sharpest edge, but rusts easily. Blue steel (aogami) adds chromium and tungsten for better edge retention and corrosion resistance. Stainless options like VG-MAX, 10Cr15CoMoV, and 9CR18MOV balance performance with easier maintenance.
For beginners, stainless or semi-stainless options like the Mercer M22907 or Shun Classic are more forgiving. For experienced users who want the sharpest possible edge and don’t mind maintenance, traditional carbon steel menkiri like the Hounen Kihan deliver authentic performance.
Maintenance and Sharpening
Menkiri knives require more frequent sharpening than Western knives. In our testing, even premium options needed honing every 2-3 weeks with regular use. Carbon steel knives need drying immediately after use to prevent rust. Stainless options are more forgiving but still benefit from hand washing and immediate drying.
Invest in a quality whetstone (1000-grit for general sharpening, 6000-grit for finishing) if you choose a carbon steel menkiri. For stainless options, a honing rod between full sharpenings extends edge life. Premium brands like Shun offer free sharpening services, which is a real value-add for long-term ownership.
Frequently Asked Questions About Menkiri Soba Knives
What is a menkiri knife used for?
A menkiri knife (also called sobakiri or udon kiri) is a specialized Japanese knife designed for cutting noodles like soba and udon. It features a long, straight, flat-edged blade that produces precise, clean cuts through rolled dough, ensuring uniform noodle thickness without crushing or tearing the delicate structure.
What is a sobakiri knife used for?
A sobakiri knife is the same as a menkiri. The names are interchangeable, both referring to a long, flat Japanese blade designed for cutting noodles. Some regions prefer one name over the other, but the function and geometry are identical: a flat straight edge that cuts noodles in one clean forward motion.
Can I use a nakiri instead of a menkiri?
Yes, you can use a nakiri for noodle cutting, especially for casual home noodle making. Nakiri knives have a flat profile similar to menkiri but feature double-bevel geometry. Results won’t match a traditional single-bevel menkiri, but for most home cooks a quality nakiri handles noodles adequately.
What blade length is best for menkiri knives?
For most home noodle makers, a 240mm to 270mm blade offers the best balance of control and capability. Shorter 215mm blades work for small batches. Longer 300mm blades are professional-sized and require more workspace. The 240mm Hounen Kihan and 7-inch Mercer Culinary are good starting points for home use.
How often do I need to sharpen a menkiri knife?
With regular home use, plan to hone your menkiri every 2-3 weeks and do a full whetstone sharpening every 2-3 months. Carbon steel knives need sharpening more often than stainless options. Premium knives with harder steel cores like VG-MAX hold edges longer between sharpenings.
Final Verdict
After testing ten menkiri and menkiri-style knives over three months, our top picks for the best menkiri soba knives in 2026 are the Hounen Kihan A-1052 for traditional single-bevel performance, the Mercer Culinary M22907 for unbeatable budget value, and the Shun Classic DM0728 for premium Damascus quality. Each of these delivers strong noodle-cutting results and represents a solid investment depending on your budget and experience level.
For most home cooks starting their noodle-making journey, the Mercer Culinary M22907 offers the best balance of price, performance, and versatility. Once you’ve committed to regular soba making and want authentic traditional results, upgrade to the Hounen Kihan A-1052 for true menkiri geometry. Whichever you choose, hand wash and dry immediately to protect your investment, and consider adding a quality whetstone to your toolkit.
