I give up, for now. I've tried everything I know and a lot of what you guys have told me, but I can't get these Zwickey Black Diamonds sharp. I always prided myself on being able to put a good edge on my knives, and when I shot Grizzlies, they were shaving sharp. I don't know what else to do with the Zwickeys. I've used files, steels, hard stones, soft stones, leather, cardboard, and every combination of these imagineable. I shouldn't have to go out and buy a $100 sharpener to put an edge on these. Bow season starts in two days, so I guess I'll just shoot some Thunderheads that I've got put back. I'll give it another try on the Zwickeys later, but for now I'm really put out with them.
