This is a well weighted hammer and as it is raw leather it will not scratch the metal I am working on (I am making a ring and I needed something to help me with sculpting helps metal on a ring-shaped mandrel). However, and maybe that's what all rawhide hammers are, it's covered in this resin that seems to flake off when I use it. It allowed me to achieve what I set out to do, so it's working great.
