Well, the handle can be from pipe, as long as you don’t smash something hard with it, like iron or steel stuff. Iron pipe would add more weight, making it bit more dangerous, but that head itself is heavy, and wood handle swallows excessive vibration, that’s why they make them like this. Maybe make the handle from something plastic?
