A peening hammer is one of those tools that shows up across a surprisingly wide range of trades - blacksmithing, automotive work, jewelry making, machinery maintenance - and this German Military issue example is built to handle all of them. The solid steel head offers a ball-peen end for dishing and spreading metal, and a cross/straight peen end for stretching or bending in a specific direction. The wood handle keeps things comfortable through extended use. Solid steel head; wood handle Ball-peen end for dishing and spreading metal Cross/straight peen end for stretching and bending metal
