Sakai Takayuki Gintan Ginsanko Left-handed Yanagiba 270mm with Saya

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.

Ginsan, also known as Silver 3, is a stainless steel from Proterial, the Yasugi Specialty Steel division. Proterial describes it as a stainless steel which has hardness and sharpness comparable to carbon steel, and lists its uses as kitchen knives and scissors.

Knife makers use it when they want the corrosion resistance of a stainless together with the hardness and sharpness that Proterial compares to carbon steel. The steel maker lists 59 HRC or over after hardening, but that is a heat treatment figure, not a finished knife figure.

Dry it after use, like any stainless knife. Its performance depends on the heat treatment and construction of the specific knife, not the steel name alone.

Yes. Proterial lists the steel as GIN 3 with 13.00 to 14.50% chromium, above the Japan Stainless Steel Association's 10.5% minimum for stainless steel.

Proterial describes it as a stainless steel with hardness and sharpness comparable to carbon steel, used in various kitchen knives and scissors, and the association notes that stainless, strictly, means it rusts less. Wash the knife and dry it after use.

Sakai Takayuki (堺孝行) is a brand of Aoki Hamono Seisakusho (青木刃物製作所) in Sakai, Osaka, and the company's own page says so directly. The trademarks for 堺孝行 and 堺菊孝 were registered in 1964.

The company started in Osaka in 1947 as a wholesaler of Sakai forged knives, set up a sales office in Sakai in 1963, and built a factory in Sakai in 1977. So when you see the Sakai Takayuki name, that is Aoki Hamono's own line.
