It is like the commander and the cqc7a-a double grind, but only sharpened on one side. Annoying to cut paper with, but it cuts other stuff like a bastard!
I love my mach-1 and carry it more than anything else. I have a buddy trying to sell a non-blackt one right now if you are interested-not sure of the price but I'm sure he'd work with you.
cheers,
Derek
