Okay, I live in florida where blacksmithing tools are almost non-existent at flea markets. Everything I have and know about are really only things I had to make out of necessity. I picked this up really cheap, and I wasn't about to leave it since it's a Heller (my favorite hammer brand :P) and it's so uncommon to find any good tools around here. However, in my year and a half of blacksmithing, I have never needed one of these. I see that it's struck with another hammer and the end of it is similar to a cross-peen, but can somebody tell me exactly what you'd use this for? I've tried searching, but when you don't know the name of the type of hammer it's really difficult to find it.
