Why own several different hammers when ONE will do. You have everything you need in this nifty 6-in-ONE hammer. A variety of interchangeable heads will get the job done: brass, nylon, rounded dome, flat, standard head, curved head. Great for leatherwork, woodwork, gunsmithing, hobbies and more. Overall about 7 1/2" tall, with the heads being approximately 1/2" in diameter.
