mine have many differant names but mostly just their pattern, my main forging hammer (a 2lb right hand diagonal pein hammer made by rthibeau) is named crunch because the first day i had it my dad tried to drive a nail with it and the face was too rounded, it skipped off the nail and broke his finger (hence the crunch) and every day that i am at the forge for more than an hour it gets a diagonal line burnt into the handle. when the handle has too many lines to hold anymore, i will remove the handle and get a new one, stain and laquer the old one and hang it on the wall of my shop
