This Kanehide bunka
made with PS60 steel which Hitachi makes for the razor industry and has a dominant share of the market worldwide. Kanehide was able to increase the hardness to HRC 60-61 through special heat treating and also increasing the wear resistance by giving the blades by using a cryogenic treatment with liquid nitrogen at minus 180 degrees C. The sub-zero treating works to change retained austenite to martensite, as a result, it is effective not only to enhance the hardness but also the wear resistance.
The result is a fully stainless knife that sharpens extremely well and cuts great. It features a nice, custom handle made by our woodworker.
