I wouldnt throw them away but keep them for practice. Its a good idea to replace the blade if your going to hunt with them. If your able to resharpen the blades then you can maybe use them for hunting. If my blades wont shave hair off my arms then they are not good enough for me to hunt with. IF you take a dull broadhead and push it through a stretched out strand of rubber bands what happens? Nothing, but if you take a razor sharp broadhead and push it through the stretched out strand of rubber bands what happens. You slice the rubber bands. If Iam hunting I will only use razor sharp boadheads.
