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.
VG-10 is a stainless steel produced by Takefu Special Steel in the early 1960s and is still in use more than 60 years later. This steel was specially designed for knife making and is used by many master blacksmiths in Japan. Despite the 15% chromium in the composition which gives it a high corrosion resistance, VG-10 can reach an HRC of 60-61. This is due to the addition of 1.5% Cobalt which gives the steel a higher hardness with a high temperature quenching treatment.
