Description

Tsunehisa kurouchi AS kiritsuke 210mm is a typical Japanese blade. Traditionally forged with a single bevel, but today there are many double bevel versions, so with a symmetrical grind. This blade is a hybrid between the Usuba and Yanagiba.

History and curiosity

Tsunehisa is a brand, like many others in Japan, which takes care of marketing the proven creations of several blacksmiths, based in different cities, such as Sakai, Tosa or Seki for example.

Each city has its own style in the creation of kitchen knives, and also specializes in the use of certain steels, more than others.

For example, Tosa craftsmen are recognized for having an excellent mastery in the forging of Ginsan and AUS10 steels. At Seki are highly recognized for the incredible work done on VG10 steel blades. And Sakai for specializing in single bevel blade forging.

This blade that we offer you today is part of the “Nashiji” series. The word Nashiji translates to “pear skin”, as the finish of the blade has a texture similar to the skin of a pear.

The core is made of Aogami Super steel, with a stainless steel coating. Aogami Super is the most efficient of Aogami steels, with a hardness that can range from 63 to 65 HRC. It is able to acquire an extremely sharp edge and retain it for a long time due to its hardness. In addition, it remains very easy to sharpen.

The handle

The handle is made by us in stabilized and dyed black ash burl, spacers in red jasper stone and brass.
