This knife has a Blue (Aogami) #2 Steel cutting edge wrapped in soft iron steel. This gives an incredible and durable HRC of 61-63. The handle is Japanese oak with Stainless ferrule.
Blue (Aogami) #2 (Hitachi Metals Ltd.) is made by adding Chromium and Tungsten / Wolfram to White Steel #2. This results in increased toughness and the production of hard carbide molecules, which improve edge retention. Many knife users have noted that while Blue Steel #2 is very similar to White Steel #2 in edge sharpness, it has slightly superior edge retention.
Black-finish is a state in which the surface that has been blackened by quenching is sharpened only with the blade, leaving the black side unintentionally on the sides (Mine and Hira) other than the blade.
There is no elegance like a polished finish, but it has a taste of bumps and ruggedness. It also has the advantage of less rust than a polished finish.
- After use, maintain it with a Whetstone or special oil for cutting tools, and store it in a dry place.
- Recommended keeping the sheath and blade separately.
- These items are not for those below 18.
