Sujihiki translates as "flesh slicer", which describes its role well. Typically 240mm to 300mm long and 34mm to 40mm high, the sujihiki blade is perfect for making long cutting movements from heel to toe. A lower blade height decreases friction when cutting and will keep the fibers of the protein you are cutting as intact as possible.
Ginsan is a steel very similar to Shirogami 2 in its composition. An addition of 14% chromium results in a stainless steel with low impurities. As a result, blades forged from Ginsan have a high hardness and cutting retention capacity that rivals most blades made from traditional high carbon steels. The purity of Ginsan makes it a preferred steel for blacksmiths who work with steel in the traditional way and is pleasant to sharpen.
