Leather head only 2.5 inches long. The head and handle (extremely light/cheap wood) weigh a total of 3.4 ounces. Hardly a "hammer" to add a lot of weight to what you do. The leather head is coated with a thick, coarse varnish or resin that damages metals. Tried a hammer on a strip of sterling silver to smooth out some of the edges and the silver was scratched horribly by the plated surface. I recommend you avoid this with jewelry or if you need a hammer with stuff. it's coming back Ron
