The M1 titanium handle milled steel head curved grip framing hammer, with its revolutionary design, is the first of its kind to feature a replaceable grip (curved or straight) and a replaceable steel head (milled or smooth). That's right, the M1 framing hammer is the last hammer you will ever need. The sleek and attractive design touts a removable all-steel head that refrains from loosening even after the toughest abuse. The M1 has a heavy, forward-weight head in either a smooth or mill faced option that allows the user the ability to deliver a powerful strike, and, with its titanium shock reducing frame, the least possible recoil. Believe us, your arm will thank you. The revolutionary interchangeable heads can be changed within seconds and lock in place for the strongest hold. The design features a new and improved side nail puller as well as an angled face made for a satisfying hit every time. Experience the future of tools with a Martinez Tools hammer.
