The Kiritsuke

What a kiritsuke is, and what the name means

A kiritsuke (切付) is, in its traditional form, a long single-bevel Japanese knife with a flat cutting edge and an angular reverse-tanto tip. It is usually described as a hybrid of two single-bevel specialists: the yanagiba, the long slicer used for sashimi, and the usuba, the professional vegetable knife. One blade, two disciplines.

The name is built from two common Japanese verbs: kiru (切る, to cut) and tsukeru (付ける, to attach or apply). The compound is usually glossed simply as "to slit" or "to cut off." As with many Japanese knife names, the etymology is descriptive rather than poetic, and sources differ on the exact nuance, so we hedge here rather than invent a tidy story.

What is not in dispute is the knife's cultural weight. In traditional Japanese restaurant kitchens, especially in formal kaiseki settings, the kiritsuke is by custom the blade of the executive chef. A cook does not simply buy one and start using it at a traditional station; the knife signals that its owner has earned command of both the yanagiba's slicing work and the usuba's vegetable work. It is often described as a status symbol as much as a tool. That custom is a convention, not a law, and it applies to the traditional single-bevel knife, not to the Western double-bevel version.

The two knives that share the name

• Traditional kiritsuke: single-bevel, typically 240-270mm (longer exists), flat profile, reverse-tanto tip, carbon steel, wa-handle. A demanding specialist's blade.
• Western "kiritsuke" (kiritsuke-gyuto or k-tip gyuto): double-bevel, typically 210-240mm, gyuto geometry with the kiritsuke's angular tip grafted on. An everyday chef's knife with extra visual drama and a more precise point.

Retail listings frequently blur the two. If a product page says "kiritsuke" and the knife is double-bevel, stainless, and priced like a gyuto, it is a k-tip gyuto. That is not a scam, and k-tip gyutos are genuinely good knives. But it is not the executive chef's blade, and buying one does not require the skills the traditional knife demands.

Anatomy and geometry

Start with our Japanese knife anatomy guide if terms like spine, heel, and shinogi are new. The kiritsuke's silhouette is defined by three features:

The reverse-tanto tip (k-tip)

Instead of a spine that curves down to meet the edge, the kiritsuke's spine runs straight and then drops in a hard angled line to the point. The result is a sharp, acute tip set low on the blade, excellent for precise entry cuts, scoring, and fine detail work. This tip is the knife's visual signature, and it is the one feature both the traditional and Western versions share.

A long, flat edge

The traditional kiritsuke's edge is nearly straight, closer to an usuba or yanagiba than to a curved gyuto. Flat edges reward push cuts and long pulling slices; they punish rock-chopping. The Western k-tip gyuto usually keeps a little more belly curve, which is one reason it is easier to live with.

Single-bevel grind (traditional form)

The traditional knife is ground on one side only. The front face carries the bevel and the shinogi line; the back face is close to flat with a subtle concave hollow (the urasuki) that reduces friction and helps release food. Single-bevel geometry is what gives the yanagiba and usuba their surgical cutting quality, and the kiritsuke inherits it, along with all of its handling and sharpening demands. We cover the implications in section 04 and in our dedicated single vs double bevel guide.

Weight and balance vary with construction, but traditional kiritsuke tend to feel long, thin, and blade-forward, closer to a yanagiba than to a Western chef's knife.

What a kiritsuke is for

The traditional kiritsuke exists to let one knife do two stations' worth of work:

• Slicing raw fish. The long flat edge draws through a fillet in a single pull, the way a yanagiba does. The single bevel leaves a glassy cut surface, which matters for sashimi presentation.
• Vegetable work. The flat heel section functions like an usuba: thin sheets (katsuramuki-style peeling is possible with practice), fine julienne, and clean push cuts through dense vegetables.
• Detail and tip work. The low, acute k-tip scores, trims, and makes decorative cuts with unusual precision.

In a traditional kitchen this versatility is the point: the executive chef oversees every station, and the kiritsuke is the one blade that follows them across all of it.

What the Western k-tip gyuto is for

Everything a gyuto is for: onions, herbs, proteins, general prep. The k-tip adds better scoring and detail precision and subtracts a little tip strength (the acute point is more fragile than a gyuto's). Functionally, think of it as a gyuto with a sharper pencil.

What neither knife is for

• Bones and frozen food. Thin, hard Japanese edges chip. Use a deba for fish butchery and a honesuki for poultry joints.
• Rock-chopping on the traditional flat-edged version. The profile has almost no belly to pivot on.
• Prying, twisting, scraping sideways. Same rule as every thin Japanese blade.

Single vs double bevel: the decision that defines this knife

For most knife types the bevel question is a footnote. For the kiritsuke it is the entire identity of the knife, so read this section before buying anything with the name on it. Our single vs double bevel guide goes deeper on the mechanics.

The single-bevel kiritsuke

Ground on one side only, the traditional kiritsuke cuts with a natural steer: the blade wants to drift toward the flat (ura) side as it descends. Skilled users compensate by angling the knife and letting the geometry work for them; unskilled users get wedge-shaped carrot slices and frustration. Add the flat profile and the length, and you have a knife with a genuinely steep learning curve. That is exactly why the kitchen custom exists: mastery of this blade implies mastery of the two knives it replaces.

• Pros: extraordinary edge acuity, pristine cut surfaces on fish, true usuba-style vegetable capability, and the tradition itself, if that matters to you.
• Cons: handed (a right-handed grind is wrong for a left-handed user, and left-handed versions cost more), steers in untrained hands, demands single-bevel sharpening skills, almost always reactive carbon steel.

The double-bevel "kiritsuke"

Ground on both sides like a gyuto, the Western kiritsuke has none of the steering behavior and none of the ceremony. It sharpens like any double-bevel knife, works for either hand, and tolerates normal home technique. What you keep from the traditional knife is the flat-ish profile and the k-tip.

Kiritsuke vs its siblings

Every knife in this table has its own canonical page. The two kiritsuke variants are listed separately because, as this whole page argues, they are different knives.

Useful shortcuts: a sujihiki is the double-bevel answer to the yanagiba, and it is what most cooks who "want a kiritsuke for slicing" actually need. A bunka is the k-tip look in a friendly 170mm home format. And if the tip is not what draws you, a plain gyuto remains the most versatile single knife you can own.

Typical steels and construction

Traditional single-bevel kiritsuke

These follow the same conventions as yanagiba and usuba. The overwhelming majority are carbon steel: shirogami (white steel) for the purest edge and easiest sharpening, or aogami (blue steel) for more edge retention. Construction is usually kasumi: a hard carbon-steel edge layer forge-welded to soft iron cladding, which keeps the blade sharpenable and gives the classic misty finish. Fully mono-steel honyaki versions exist at collector prices. Ginsan (Silver 3) appears when a buyer wants single-bevel behavior in stainless. Our blade construction guide and steel guide map this territory in full.

Western double-bevel kiritsuke

These follow gyuto conventions instead: stainless or clad stainless steels such as VG-10, AUS-8 and AUS-10, and SG2/R2 powder steel at the enthusiast tier, plus carbon options like Aogami Super from smiths who forge them. San-mai cladding, Damascus layers, and kurouchi finishes all show up here, exactly as they do on gyutos.

Handles skew traditional: most kiritsuke of either bevel wear an octagonal or D-shaped wa-handle, which suits the blade-forward balance. Western-handled k-tip gyutos exist but are the minority.

Who makes good ones

Names below link to our maker guides. This is not a shopping list of everything on the market, just houses we have profiled whose kiritsuke work is well established.

• Masamoto. The Tokyo house's single-bevel kiritsuke in white steel (the KS line) is one of the most recognized traditional examples, offered in the classic 240mm and 270mm sizes.
• Sakai Takayuki. Sakai's flagship brand covers the full single-bevel catalog, kiritsuke included, across kasumi and premium grades.
• Sakai Ichimonji Mitsuhide. A professional-focused Sakai house with deep single-bevel expertise; a natural place to look for a traditional kiritsuke.
• Moritaka. Their kiritsuke is the other kind: double-bevel, Aogami Super core, kurouchi finish, symmetric 50/50 grind. A hand-forged k-tip workhorse rather than a ceremonial blade.
• Tojiro. Offers accessible double-bevel kiritsuke-profile knives, a low-risk way to find out whether the flat profile and k-tip suit you.

General rule: for a traditional single-bevel kiritsuke, buy from Sakai houses or Masamoto, the same makers you would trust for a yanagiba. For a double-bevel k-tip, judge it exactly as you would judge a gyuto from the same maker.

Choosing a size

• 240mm (traditional): the entry size for single-bevel kiritsuke. Long enough for clean pull-slices on fish, short enough to control on a home board.
• 270mm (traditional): the classic professional size. Wants a board of at least 40cm and a cook who is comfortable with long blades. Sizes up to 300mm and beyond exist for line work in restaurants.
• 210mm (double-bevel): the friendliest k-tip gyuto size for home kitchens, comparable to an 8 inch chef's knife.
• 240mm (double-bevel): the sweet spot for cooks who already like a 240mm gyuto and want the flatter profile and angular tip.

Two cautions. First, the flat profile makes a kiritsuke feel longer than a curved gyuto of the same measurement, because more of the edge engages the board at once. If you are between sizes, go shorter. Second, remember the acute tip is delicate at any length; storage matters (a saya or magnetic strip, never a loose drawer). Our knife size guide covers board-to-blade matching in more detail.

Sharpening and care

Single-bevel: a different discipline

A traditional kiritsuke sharpens like a yanagiba: you work the front bevel along the shinogi at the blade's own geometry, then deburr the flat back with the stone laid almost dead flat, preserving the urasuki hollow. You do not grind a symmetric 15 degree edge onto it, and you should not hand it to a pull-through sharpener under any circumstances. If you have never maintained a single-bevel knife, budget real practice time or find a professional sharpener. Our whetstone sharpening guide covers stone selection and technique, and our sharpening angles guide explains the geometry.

Double-bevel: standard Japanese-knife care

The k-tip gyuto sharpens like any double-bevel Japanese knife: whetstones, roughly 12-15 degrees per side, strop or fine stone to finish. The only special note is the tip itself: the acute point grinds away quickly if you are careless on the stone, so give it light, deliberate passes.

Daily care, both versions

• Hand wash, dry immediately. Carbon-steel versions will rust if you walk away wet; expect and embrace a patina instead (see our patina guide).
• Wood or soft plastic boards only.
• Store in a saya, on a magnetic strip, or in a block. The k-tip is the first casualty of a knife drawer.

Who should buy one

Buy a traditional single-bevel kiritsuke if: you already own and sharpen single-bevel knives, you prepare sashimi and fine vegetable work regularly, and you want (or have earned) the one-blade tradition. It is a destination knife, not a starting point.

Buy a double-bevel k-tip kiritsuke if: you want a gyuto-class daily driver with a flatter profile, better scoring precision, and, honestly, the look. There is nothing wrong with loving the silhouette; just know what you are buying.

Skip both if: you rock-chop heavily (get a gyuto), you mainly want a long slicer (get a sujihiki), or you want a compact all-rounder (get a santoku or bunka).
