The honesuki (骨スキ, from hone “bone” and suki “to cut or scrape”) is the Japanese boning knife, built mostly for poultry. It grew out of Japanese kitchens that cook a lot of chicken, especially yakitori shops, where whole birds are broken down every day. Its bigger sibling, the garasuki, is used for heavier bones and larger birds.
Blade shape and geometry
A honesuki is short and triangular. The spine runs straight to the tip, the edge is nearly straight, and the blade is tall at the heel, around 35 to 40mm, then tapers to a sharp point. It is stiff, not flexible, and the spine is thicker than a petty’s.
Traditionally it is ground asymmetrically or single-bevel, with most of the bevel on the right face. That lets the flat left face ride along the bone. Many knives sold outside Japan are double-bevel or asymmetric, so check the listing or ask. The tall heel gives knuckle clearance and a strong section for pushing through joints, while the point handles fine work around the carcass.
What it is for, and what it is bad at
The honesuki is for whole chickens, ducks, and game birds: cutting through skin, finding and separating joints, taking breasts off the frame, and removing thigh bones for yakitori or karaage. It also works for trimming pork tenderloin, removing silver skin, and boning out small cuts of lamb or pork.
It is not a cleaver. It is bad at splitting spines, chopping through leg bones, or hacking frozen poultry. It is also poor for board prep. The triangular shape and short edge make it awkward for vegetables. For whole fish, the deba is the better tool.
Common lengths and which to choose
| Length | Good for |
|---|---|
| 135mm | Smaller hands, small birds, detail work |
| 150mm | The standard, whole chickens and most meat trimming |
150mm is what most people should buy. It is long enough for a large chicken and still easy to control.
Bevel and handedness
This is where honesuki vary most. Traditional single-bevel or strongly asymmetric honesuki are made for right-handed use. Double-bevel versions suit either hand. Left-handed cooks should confirm the grind before buying. Our single bevel vs double bevel guide explains the difference.
Steel recommendations
A honesuki works in raw meat, fat, and around bones, so toughness and rust resistance matter more than extreme hardness. Stainless is the practical choice. The Masahiro MV honesuki from Seki is a stainless, professional-oriented option. VG-10 and AUS-10 are also sound.
Very hard steels like ZDP-189 or Aogami Super are a poor match, since they chip more easily when they hit bone. Carbon Shirogami #2 honesuki exist and sharpen easily, but they rust fast in chicken juices. Most honesuki run $90 to $200. Prices move with the yen.
Who should buy one, and who should skip it
Buy a honesuki if you buy whole chickens to save money, make yakitori or karaage at home, or cook in a restaurant that breaks down poultry. It also protects your gyuto from the bone work that would chip it.
Skip it if you buy boneless cuts from the store. A petty covers light trimming, and you will not use the honesuki’s strength.

- Petty: the small utility knife for trimming, without the stiffness for joints.

Frequently asked questions
What is a honesuki knife used for?
A honesuki breaks down poultry. It separates legs and wings at the joints, removes breasts from the frame, and debones thighs. It also trims and bones smaller cuts of meat.
How is a honesuki different from a Western boning knife?
A Western boning knife is narrow and often flexible. A honesuki is stiff, triangular, and harder, so it works more like a small, precise blade for cutting along bones and through joints.
Can a honesuki cut through bone?
It cuts through cartilage and joints, not solid bone. Use the heel or a cleaver for spines and thick bones, and keep the honesuki for precise work around them.
