I use it for car/truck work I had a 5 lb hammer and it grew legs once so I upgraded it to 6 lbs, 1 lb really does make a difference in your forearms if you use it several hours a day. For my work I want it to be more square on the ends, round and slightly beveled impact points tend to make it slip off non-flat things. The handle is comfortable with little impact on the wrist and has not broken yet, a couple of times I have broken the handle not the head.
