Comparing Steel

8CR13MoV & 8CR14MoV - Actually these grades do not have a very big difference. They are similar to AICHI AUS-8, an excellent value priced steel for its performance.

AUS-8 (8A) is comparable to 440B with a carbon content close to 0.75%.[8] AUS-8 is often used instead of 440C.[8] SOG knives uses AUS-8 extensively
