Sujihiki translates as "flesh slicer", which describes its role well. Typically 240 mm to 300 mm long and 34 mm to 40 mm high, the sujihiki blade is perfect for making long cutting movements from heel to toe. A lower blade height decreases friction when cutting and keeps the fibers of the protein you are cutting as intact as possible.
Super Gold 2 or SG2 is a powder metallurgy steel designed by Takefu Special Steel Co Ltd in Takefu, Echizen/ Fukui. It is a high-carbon stainless steel that is pulverized to a very fine grain size and then put back together. This process results in a homogeneous grain structure of the steel, making it easier to sharpen and very durable. Takefu Steel is the company that also created the popular VG-10 steel. The goal behind the design of SG2 was to offer a range above VG-10, which proves to be the case in all aspects.
Being able to reach a hardness of 64 HRC and thus obtaining a breathtaking edge, the SG2 is very famous in the world of Japanese cutlery.
