Martin General Purpose Dinging Hammer Model 150G
Product Review (submitted on May 6, 2013):
I still have a lot to learn about sheet metal forming but bought this hammer to get me started. Wasn't interested in cheaper tools or fiberglass handles, so ended up with this one. Feels good in your hand, nice and balanced and doesn't ring. So far it's served me well straightening sheet metal flanges. In skilled hands I'm sure it'd be extremely effective.
