For a stainless blade and in this case the NitroV, that is hardened by heating to 1950F for 15 minutes and plate quenched then tempered at 300F twice, the finished blade will have a R hardness of about 60R but the same blade if given a liquid nitrogen cryo quench before the 2 tempering cycles will be up in the 62R plus range which not only add hardness but also toughnes to the blade. Expensive to set up with the Dewar and LN but adds to the quality of the blade that can be produced.Von Gruff, I'm familiar with "cyro" treating of gun barrels making them more accurate, but what does it do for knives?
@arizonajake I’ve handled one Kiwi hunting knife knife with a a Micarta handle belongings to an Aussie.@arizonajake That is a valid point and a micarta handle that is shaped to be secure in hand and with a 120grit finish can still look good without the need to have suplementary griping added. There are some who add gripping areas with round file etc but knife design and that is the whokle knife design has a direct bearing on the usability and therefore the safety of use. Wiping wet or bloody hands periodically when they become slippery is a sensible precautionary safety practice that can and does prevent many instances where weak hold on the knife may cause harm to the user.
