Yoshimi Kato Ginsan Tsuchime Honesuki Double-bevel 150mm

A honesuki (骨スキ) strips meat from the bone, the job a boning knife does elsewhere.

One Japanese knife maker describes the traditional honesuki as a shape unique to Japan, made with Japanese knife techniques and ground single-bevel (片刃), so it can also be used to prepare fish.

A standard single bevel knife is ground for right-handed use, and a left-handed one is made with the bevel reversed. Some makers offer left-handed versions.

Ginsan steel, also known as Silver #3 or G3, is a stainless steel made by Proterial in Japan, containing 0.95 to 1.10% carbon and 13.00 to 14.50% chromium, and it is used in Japanese knives because it combines the sharpness and ease of sharpening of carbon steel with the rust resistance of stainless steel. It is a fine-grained steel that takes a very sharp edge, and rated by Proterial at over 59 HRC, it offers a practical balance of edge retention and sharpenability for everyday kitchen use.

The name "Ginsan" (銀三) literally means "silver three," referring to its Silver #3 designation. Its moderate chromium content makes it far less reactive than carbon steels, so it won't discolor or rust as quickly, while its carbon content keeps the edge keen and responsive on the stones. For home cooks and professionals who want a stainless knife that still feels like a traditional Japanese blade, Ginsan is a common middle ground.

Yes. Proterial lists the steel as GIN 3 (銀紙3号) 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.

Yoshimi Kato is known for hand-forged Damascus knives with thin geometry and strong cutting performance, working primarily in SG2 and Aogami Super steels from his workshop in Echizen's Takefu Knife Village. He is the third-generation representative of Kato Knife Manufacturing, which was established in 1948. His reputation rests on precise heat treatment of premium steels and distinctive Damascus patterns.

Kato also produces knives for the Masakage brand. In recent years he has drawn inspiration from his friend Yu Kurosaki, another Takefu Knife Village smith, and developed newer designs such as the Hyo line. His new gallery and workshop recently opened next to Kurosaki's gallery in Takefu, reflecting the close creative relationship between the two makers.

Yes. Yoshimi Kato is the third generation of a smithing house in Echizen, Fukui, founded in May 1948, and he is its representative today.

The company, Kato Uchihamono Seisakusho, is in Echizen City, with its knife department at Takefu Knife Village. The first generation founder was a certified traditional craftsman, and the second generation began knife smithing in 1949.

The company writes his name 加藤義実, so that is the form on its own materials. The form 加藤義實 uses the traditional character for 実.

Both spellings name the same smith, so either search brings you to the same maker.
