The founder of Tadafusa, Sone Torasaburo started the company from nothing in the 23rd year of the Showa era in 1948. He made various kinds of knives such as sickles, short swords and kitchen knives by using the forging techniques he learned as an apprentice making hand-forged metal scales. He gradually started to specialize in making fishing knives and then also address a need to create kitchen knives for home and professional use and special knives for Soba up to today. Since the company’s foundation, they strive to create “the best products” for customers by hand through every single process and to make each knife with utmost enthusiasm.
The SLD Hammer tone series has one of the most distinctive hammered patterns in Japanese knife making. Each blacksmith has its own Tsuchime pattern. Their Tsuchime is based on geometric diamond pattern, which has been familiar from ancient times in Japan.
Hitachi SLD Steel has more chromium than carbon steel such as Blue Paper Steel or White Paper Steel, which means that it is more resistant to rust but not fully stainless (semi stainless). Also, it holds a sharp edge and a long edge retention by its hardness and toughness. It is popular steel for kitchen knives in Japan.
The Hiraki or Kaisaki is a special knife that can be used as a shellfish knife or filleting small fish. Can also be used as a small general use knife.
