I did some research and found a product that a guy here used. It's a gel from Wal Mart called Klean Strip.
I applied it to the ground portion of my blade and it worked like a charm. The black rubbed right off.
Now that I've done this, I'm not happy with how it turned out...go figure, right? So, I'm going to do the entire blade, and hopefully I'll be able to keep the USMC and KaBar stamps black while the rest of the blade will be bare metal.
I haven't decided wether I'll polish the rest of the blade or maybe use some sort of finish, like mustard.
I'm having fun with it.
