This is almost the same rock Hammer as the Estwing Supreme 22 oz Pointed Tip Rock Hammer E3-22P. The difference is the use of a leather handle rather than the vinyl handle. The leather grip is made of laminated leather "O" rings pressed then riveted to the shaft. The whole handle is then laminated. The leather grip makes this hammer aesthetically pleasing as well as a great field tool. The leather is factory coated with a varnish that wears off with use.
