One day a 16oz. carpenters hammer may be banned because the wooden handle was changed to black fiberglass/plastic. Looks like an evil hammer, nope, you cant have that !! And the reason will be : It makes for a faster swinging hammer. Lol !!
Why do you need a modified hammer, SUMIKITO, huh? huh? If you were an honest, innocent citizen you wouldn't need a modified hammer. You should be satisfied with this stock plastic hammer. After all, only criminals would ever want a hammer that can be used faster, more efficiently, and with greater hammer-power.
