I gotta agree with N1; I bought a couple of the Cold Steel machetes, and for $20 a piece, they do what I want them to do. They're nothing pretty, they're beaters that I'll continue to beat and abuse until they're useless, and then I'll toss 'em in the junk.

Get a belt sander and just rough grind the edge on it so it's sharp enough for hacking; that's what they're worthy of, nothing more.
