What is a yanagiba?
A yanagiba (柳刃, "willow blade") is the traditional Japanese slicer for raw fish. It's long (240–330 mm, with 270 mm the common size), slender, and ground on one side only with a flat, subtly hollowed back. That single bevel lets it take an extraordinarily keen, acute edge — exactly what slicing delicate raw fish demands.
The pointed style is the Kansai (Osaka) form; the Kanto (Tokyo) version, with a squared-off tip, is called a takobiki. Either way, this is a knife built for one job — turning a fillet into clean, glossy slices — not a general kitchen blade.
How it cuts: one long pull
The whole point of a yanagiba is to slice in a single, smooth pulling stroke — drawing the full length of the blade through the fish rather than sawing back and forth. A sawing motion tears the flesh and dulls the surface; one clean pull leaves a glossy, undamaged cut face that catches the light and tastes cleaner. That's why the blade is so long: you want to finish the slice before you run out of edge.
It rewards a light touch and a very sharp edge. What it won't do is chop, dice or handle anything but boneless fish — for that, reach for a gyuto.
Yanagiba vs sujihiki
If the single-bevel commitment sounds like a lot, the sujihiki is the easier alternative — a long, double-bevel Western-style slicer. It works in either hand, sharpens like any double-bevel knife, and slices cooked meat and roasts as well as fish.
| Yanagiba 柳刃 | Sujihiki 筋引 | |
|---|---|---|
| Bevel | Single | Double |
| Made for | Raw fish, sashimi | Meat, fish, all slicing |
| Handed | Yes (right or left) | Either hand |
| Length | 240–330 mm | 240–270 mm |
| Edge | Exceptionally keen | Very keen |
| Sharpening | Bevel + light back (uraoshi) | ~15° both sides |
| Learning curve | Steeper | Easy |
Choose the sujihiki for an easy, versatile slicer; choose the yanagiba for traditional sashimi work and the cleanest possible cut.
Single bevel, care & sharpening
Yanagiba are often made from reactive carbon steels (white or blue), so treat them like any carbon knife — wipe dry, welcome the patina, keep them out of the sink. Sharpening is different from a double-bevel knife: you work the single bevel, then take the wire edge off the flat back with a light touch (the uraoshi). If you're new to it, read single vs double bevel first.
Do you need a yanagiba?
Get one if
- You slice your own sashimi or sushi regularly
- You want restaurant-clean, glossy slices
- You're ready to learn single-bevel technique
- You'll buy it for your dominant hand
Skip it if
- You want a versatile, everyday knife
- You rarely prepare raw fish
- You'd rather not learn a new sharpening method
- An easy slicer would do — get a sujihiki
The bottom line
A yanagiba does one thing better than any other knife: slice raw fish, cleanly, in a single pull. If that's a thing you do, it's a joy. If it isn't, it'll live in the drawer.
Treat it as a considered specialist bought alongside an everyday knife — never as a first purchase. For that, start with a gyuto or santoku.
Frequently asked questions
What is a yanagiba used for?
A yanagiba is a slicing knife for raw fish — sashimi and sushi toppings. Its long, thin, single-bevel blade lets you slice a fillet in one smooth pulling stroke, leaving a clean, glossy cut face. Slicing in a single pull (rather than sawing) matters: it doesn't crush the flesh, so the fish looks better and tastes cleaner.
Why is a yanagiba so long?
Length lets you slice through a piece of fish in one continuous pull, with no sawing back and forth. A 270 mm blade is the common all-round size; home users sometimes go 240 mm, while professionals often use 300 mm or more. The longer the blade, the larger the piece you can slice cleanly in a single stroke.
Is a yanagiba single or double bevel?
Single bevel. It's ground on one side, with a flat, slightly hollowed back (urasuki), which is what lets it take such an acute, clean edge for slicing. Because it's single-bevel it's also handed — a standard yanagiba is made for right-handers, and left-handed versions exist but are rarer and usually cost more.
Yanagiba vs sujihiki — what's the difference?
Both are long slicers, but a yanagiba is single-bevel and traditional, made for raw fish; a sujihiki is the double-bevel, Western-style slicer. The sujihiki is easier to use and sharpen, works in either hand, and also slices cooked meat and roasts. The yanagiba gives a cleaner, keener cut on sashimi but demands single-bevel technique and care. If you want an easier all-round slicer, choose a sujihiki; for traditional sashimi work, the yanagiba.
What is a takobiki?
A takobiki is the Kanto (Tokyo) style of yanagiba, with a squared-off tip instead of a pointed one. It does the same job — slicing raw fish — and the choice is mostly regional and personal. The pointed yanagiba is the Kansai (Osaka) style and the more common one today.
Do I need a yanagiba?
Only if you regularly slice your own sashimi or sushi. It's a specialist knife, not a general kitchen blade — it won't chop vegetables or break down a chicken. If you love preparing raw fish and want restaurant-clean slices, it's wonderful; otherwise a good gyuto covers everyday cooking far better.
