Sukenari VG10 Damascus Yanagiba 330mm, Ebony Three Spacer Handle

A yanagiba (柳刃包丁) is a sashimi knife for slicing raw fish. A knife maker's guide says a sashimi knife cuts without breaking the fibres of the flesh, and that it is longer and narrower than other knives because slicing sashimi with crisp edges needs the length.

The whole length goes through one pulling cut. The Sakai cutlery association calls the yanagiba the sashimi knife used mainly in the Kansai region.

Size a yanagiba to the fish you prepare: a knife maker's guide gives 270 to 360 mm for professional use and 240 to 270 mm for home use, with 270 mm at home if you slice larger fish.

The guide says the whole length goes through one pulling cut, so do not choose too short a knife, and at home it points to the size of your board and your work space. We list the yanagiba (柳刃) from 210 to 360 mm, some made for left-handed use.

No. The Sakai cutlery association describes the yanagiba (柳刃包丁) edge as so acute that it cannot be used on hard things such as bones.

For bones the association describes the deba (出刃包丁), whose heel is used to hit them.

An encyclopedia describes sashimi knives as thin and narrow, calling the pointed ones yanagiba and the unpointed ones takohiki. A sakimaru takohiki is the rounded-tip variant, so it has a rounded point despite its takohiki name.

A trade body, the Sakai cutlery association, calls the takohiki (たこ引き包丁) the Kanto-type sashimi knife, and the yanagiba the sashimi knife used mainly in Kansai, with an acute edge that is not for bone.

A sujihiki is a double bevel meat slicer: long, narrow, and made for dividing larger pieces of meat into their parts and for slicing roasts. A Sakai knife maker notes that some cooks also use its shape as a double bevel sashimi knife, so it is not limited to meat.

A yanagiba is the single bevel sashimi knife, cut in one pulling stroke from heel to tip. A single bevel cuts thinner, but it needs practice and is handed. A yanagiba edge is too acute for bone or other hard things, so it stays in the sashimi role. The usual lengths differ by job: sujihiki around 240 to 300 mm, yanagiba around 270 to 330 mm.

Choose the sujihiki for meat and general slicing, with sashimi as a secondary use. Choose the yanagiba when traditional single bevel sashimi work is the main job and you are ready for the handling and sharpening that construction requires.

Yes, it can. Takefu, which makes VG10 (V金10), lists it among its stainless steels, and the JSSA notes that stainless strictly means rust-resistant, not rust-proof.

Takefu lists VG10's chromium content as 15% and describes its corrosion resistance as excellent. We recommend drying the knife after washing.

Takefu, the steelmaker behind VG10, gives HRC 60 or more as its hardening hardness, measured straight after quenching. The hardness of a finished knife depends on its maker.

Takefu says the steel's 15% chromium, 1% molybdenum and 1.55% cobalt give it high hardness and a long-lasting edge, and that it is easy to sharpen.

Both are Takefu blade steels, and they differ in class and in what Takefu publishes about each. Takefu lists VG10 as a stainless steel with 1.00% carbon, 15.00% chromium, 1.00% molybdenum, 0.25% vanadium and 1.55% cobalt, at a hardening hardness of HRC 60 or more.

Takefu describes SG2, its Super Gold 2, as a blade steel created by powder metallurgy, lists its composition as not disclosed, and SG2 runs 61 to 65 HRC depending on the maker. Takefu also calls SG2 a powdered stainless high-speed steel.
