Custom etched Finn Wolf. Probably the sexiest Cold Steel folder on earth.. unless someone has a fully engraved CS knife somewhere. I use nail polish which is extremely hard to work with. It is not conducive to any kind of detail.. detail and nail polish shouldn't even be in the same sentence and yet I somehow manage to produce knives like this. How? Patience, perseverance and a very steady hand. I plan on doing some 1911 frames and slides next!
