The STILETTO 15oz TI-BONE III Hammer with Steel Milled Face and 18 in. Curved Handle is our most powerful and most durable hammer. This 15oz full titanium hammer hits like a 28oz steel hammer, with 45% less weight and 10x less recoil shock. It is recommended for rough framing, remodeling and pole barn construction. The TI-BONE III features a 180° side nail puller that allows you to pull 6D-16D nails with ease and includes a magnetic nail starter. The STILETTO 7 in. Carpenter Square is designed with more layout notches to help you build faster. Additional notches aid in laying out 2 ft. x6 ft. material, ripping boards and marking rafter pitches. The BOMBER Cutout allows for repeatable stud measurements, while the bottom heel markings provide marking versatility. The 7 in. Carpenter Square with Level is fully machined, with an anti-glare finish and the most durable coating.
