I can - and always do - put a razor edge on all of my knives, but I have a heck of a time doing the same thing with my broadheads.

I shoot muzzys and I have several of last year's broadheads/arrows still in my quiver and they're still in perfect condition . . . except for the fact that oxidation has dulled the blades a bit.

I won't shoot a blade that isn't razor sharp and wouldn't think of shooting these in their present condition. I have replacement blades and have always just replaced them, but since the replacements cost $1.00 PER BLADE, it would be nice to touch up the ones that are already set-up IF I can get them sharp enough.

Any suggestions?
