Hey guys so this hammer I have hasn't been doing well for a while now. Only one head opens regularly and the other is always retraced and is now showing skeleton. Should I just dremel off the bad head? Should I just dip and clean the sponge/algea off of it? This hammer was originally 4 heads and I dremeled it to make two 2headed frags. Let me know what you guys think I should do, I'm not sure if it's too far gone to save or not.
