Miyazaki Kajiya x Hatsukokoro Damascus Ginsan Hakata 180mm Snakewood Handle

The bunka knife (文化包丁) takes its name from bunka, culture. A Sakai knife maker ties the name to Japan's modernisation, when Western culture and Japanese tradition merged, and says it stands for that new era and for the knife's wide range of uses.

The same maker says that as diets broadened to meat, fish and vegetables, an all-purpose knife was wanted, and the bunka took features from both Japanese and Western knives.

The tip. One Japanese knife maker describes the bunka (文化包丁, kengata) as combining the good points of the gyuto and the nakiri with the tip cut at an angle, and the santoku as coming after it, by rounding that tip.

Both are all-purpose knives for the home; santoku (三徳) means three virtues, for the three foods it cuts: meat, fish and vegetables.

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.

Miyazaki Kajiya's own site writes that its smith trained for five years from 2004 (Heisei 16) at the Ōba forge (大庭鍛冶工場) in Fukuoka, and opened the smithy on Fukue Island in the Goto Islands, Nagasaki, in 2011 (Heisei 23).

The site describes Miyazaki Kajiya (宮崎鍛冶屋) as a village blacksmith (野鍛冶) that makes Tsubaki (椿) knives and also makes and repairs farm tools.
