You could hunt with them right out of the pack, Not shaving sharp but sharp. I did take one head over a diamond stone 5 strokes per side and they were popping hair and skin at that point. They spin perfect and are very tough. I shot and hit flat rock on a hillside, it went about 50' almost straight up and 50' down range, feathers all over the ground. BH showed no damage at all, It spun perfect and not bent at all. IMHO this is the perfect 3 blade Broadhead. We may offer it in Stainless Steel later.
