United Cutlery, as a rule, make their 'knives' out of, what they call, 420 Stainless steel. It's basically one step up from plastic. It's actually a step down from whatever it is that Franklin Mint use to make 'knives'
Please don't be offended by this, but UC don't really make useable knives (Hence the apostrophies) They manufacture 'collectibles' usually found at flea markets & on the late night shopping channels.
Chances are you'll never, ever get it sharp & if by an act of God you do, the first time you cut anything it'll be blunt again. Chances are that it is in fact shaving sharp, but your arm hairs are taking the edge off. Seriously, it's that bad.
Sorry.
