Were I getting bit even once, I'd be having my hammer spur trimmed. There's not a lot of difference between manufacturers, other than wide spur and standard spur. Thewide ones may be more prone to biting, depending on your hand. Rowel hammers are a good option, but the tang of the grip safety must be cut for a clearance notch on the top. Hope this helps.
