What kind? If it's a muzzy or something similar I'd just replace. If it's a cut on contact like G-5 Montec or Bear Razor sharpen and definatly re-use. That's what I do anyway.
Good luck and maybe congrats?
If they are replaceable blade heads change the blades. If they are fixed blades, sharpen. Always change ur blades or sharpen them after shooting the head into something.
