Chef knives made by Toshu have all of five features that finest kitchen knives must have. Toshu makes knives using traditional Japanese swordsmiths’ techniques, “Hizukuri Forging” and “Edo-Togi grind”.

Toshu Super Blue Steel chef’s knives are ones made of the highest quality steel. Although they look like ordinal kitchen knives at first glance, their cutting performance is second to none. To begin with, blue steels (also called "Aogami") are the strongest material among steels in the market. Blue steels are increased wear resistance and stickiness compared to ordinal white steel, by adding chromium and tungsten. Their rockwell hardness (HRC) is over 60 (very hard). Super blue steel surpasses the performance of blue steels. It is harder (cut sharper), stickier (hard to chip in a blade), and more wear resistance. In addition, super blue steel overcomes a defect, easy to chip, of blue steel. Furthermore, Toshu Super Blue Steel knives are made to be easier to use by three layer structure of the blade; super blue steel core is sandwiched by stable steel materials.
