They should still be good. However, it wouldn' t hurt to run them over a stone a bit and give them that little extra sharpness. Gotta make sure they' re lethal. I' ve gone three years without shooting a deer or using my broadheads. They are Thunderhead 100' s. Since they have replaceable blades, I just kept the original blades in the plastic case they came in and haven' t touched them. They are as sharp as the day I got them.
