About the Shape - The Yo-deba is the Western version of the traditional Japanese Deba. It is for filleting fish and butchery with boneless meat and cutting half frozen food. Yo-debas have a similar weight to Western chef knives, with the added benefit of a blade that is sharper and stays sharper longer.
About Tojiro: Tojiro is a knife-making giant in Japan. While they have a small factory that produces incredible hand-forged knives, their true specialty is factory-made knives. In Japan, “factory-made” isn’t what most people think. While the blades are rolled and stamped, much of the work is done by hand including grinding and finishing steps. Tojiro primarily works with VG-10, a stainless steel loved for its ease of sharpening and easy maintenance, but they also use VS2, SK85 and others.
