Sujihiki and yanagiba slicing knives side by side on slate with a block of sashimi-grade tuna

Sujihiki vs. Yanagiba: Which Japanese Slicing Knife Do You Actually Need?

Two long, narrow Japanese knives sit next to each other in our case. Both are slicers. Both run 240mm to 300mm. From across the room they look like the same knife. In the hand, on a board, they behave nothing alike, and we watch people buy the wrong one more often than any other pair in the shop.

The sujihiki is a double-bevel slicer built for cooked and raw proteins alike: carving a roast, portioning brisket, slicing a side of salmon. The yanagiba is a single-bevel sashimi knife built for one thing, pulling impossibly clean slices through raw fish in a single stroke. One is a Western-friendly workhorse. The other is a specialist's tool that asks for real technique.

This guide covers what each knife is, why the single-vs-double bevel difference matters more than anything else about them, what each is actually for, and how to choose the right one.

The sujihiki

Sujihiki means something close to "flesh slicer" (suji is sinew, hiki is to pull). It's the Japanese answer to a Western carving knife: long, narrow, thin behind the edge, and ground 50/50 on both sides like a gyuto. The narrow blade means less steel dragging through the food, so slices release cleanly and you get less tearing on delicate proteins.

What it does: carves roasts and whole birds, portions brisket and pork shoulder, slices a tri-tip, trims silverskin off a tenderloin, breaks down a fish fillet, and handles raw fish well enough for home sushi. If you own a smoker or cook a Sunday roast, this is the knife you've been doing it with the wrong tool for.

Because it's double bevel, it cuts straight, works for left- and right-handed cooks, sharpens like any other Japanese knife, and feels familiar within a minute. It's the easy recommendation.

The yanagiba

Yanagiba means "willow blade," for its long, slender profile. It's the traditional sashimi and sushi knife, and it's ground on one side only: a wide bevel on the front face, and a flat (actually slightly concave, called urasuki) back. That geometry is what lets a skilled hand draw the blade through a block of tuna in one pull and leave a surface so clean it looks polished.

It's a specialist. A yanagiba is used almost exclusively for raw fish, cut with a long pull from heel to tip, never a push or a saw. It's not meant for cooked meat, vegetables, or anything with resistance. Used that way it works brilliantly; used as a general slicer it steers, wedges, and frustrates.

Standard yanagiba are ground for right-handed use. Left-handed cooks need a left-handed grind, which is rarer and usually costs more. We keep both when we can.

Single vs. double bevel, in practice

This is the decision. Everything else about these knives follows from it.

  • Steering. A single-bevel edge pushes the blade sideways as it cuts. Experienced hands use that to their advantage; new hands get crooked slices until they learn to compensate. A double bevel cuts straight by default.
  • Handedness. Double bevel works for everyone. Single bevel is right- or left-specific, full stop.
  • Sharpening. A sujihiki sharpens like a gyuto, and our whetstone guide covers it. A yanagiba has to be sharpened on stones by someone who understands the single bevel and the urasuki; a honing rod will damage it, and a pull-through sharpener will ruin it. If you don't want to learn that, plan on bringing it to us.
  • Steel. Traditional yanagiba are carbon steel (shirogami or aogami), which takes the finest edge but rusts if you look at it wrong. Sujihiki come in every steel, including fully stainless.
  • Edge quality on raw fish. This is where the yanagiba wins and it isn't close. For sashimi, a single bevel leaves a cleaner surface than any double-bevel knife can.

Which one should you buy?

Buy a sujihiki if you carve roasts, smoke meat, portion large cuts, break down whole fish, or want one long knife that handles both raw and cooked proteins. That's most home cooks and most line cooks. It's also the right pick if you make sushi occasionally and want a knife that's useful the other 50 weeks of the year.

Buy a yanagiba if you make sashimi or nigiri regularly, you care about the surface of the slice, and you're willing to learn single-bevel technique and sharpening, or to have it sharpened professionally. It's a commitment. The reward is a cut no other knife can make.

Buy both if you're a professional or a serious enthusiast. They don't overlap; each does a job the other can't.

One useful middle ground: a few makers grind yanagiba-shaped knives 50/50. Moritaka's Aogami Super Yanagiba 270mm is one: the long, narrow sashimi profile with a double-bevel edge, so you get the length and the slicing geometry without the single-bevel learning curve. It's an honest hybrid, not a true yanagiba, and for a lot of home sushi makers it's the right answer.

Sizes, and what's in the case

For a sujihiki, 240mm suits most home kitchens and 270mm is the professional standard; go longer if you regularly carve whole briskets or large fish. For a yanagiba, 240mm to 270mm covers home use; sushi counters run 300mm and up.

Both knives want a saya when they're not in use; a long, thin blade in a drawer is how tips get bent. We stock sayas for 240mm and 270mm sujihiki, and single-bevel yanagiba sizes.

Still not sure? Bring in whatever you're slicing most. We'll put both knives in your hand at the shop on Oak Street and the choice usually makes itself.

Frequently asked questions

What is the difference between a sujihiki and a yanagiba?
Bevel and purpose. A sujihiki is a double-bevel slicer for cooked and raw proteins, cuts straight, and suits any cook. A yanagiba is a single-bevel sashimi knife designed for pull-cutting raw fish, leaves a cleaner slice on fish, but steers in the cut and demands technique and stone sharpening.

Can I use a sujihiki for sushi and sashimi?
Yes. A sharp sujihiki slices raw fish well and is what most home sushi makers should buy. A yanagiba produces a cleaner surface on the slice, which matters at a sushi counter and is a nice-to-have at home.

Can I use a yanagiba for meat or vegetables?
Not recommended. The single bevel steers and wedges in anything with resistance, and the thin edge is easy to chip on bones or hard vegetables. Keep it for raw fish.

Is a yanagiba hard to sharpen?
Harder than a double-bevel knife. The wide front bevel and the hollow-ground back each need to be worked correctly on whetstones, and a honing rod or pull-through sharpener will damage it. Many owners have theirs sharpened professionally; we do it at the shop.

What size sujihiki should I buy?
240mm for most home kitchens, 270mm if you carve large roasts or work in a professional kitchen. Longer blades slice in fewer strokes but need board and counter space.

Are yanagiba knives left- or right-handed?
Standard yanagiba are ground for right-handed use. Left-handed cooks need a left-handed grind, which is made in smaller numbers and usually costs more. Sujihiki are double bevel and work for either hand.
