Every pro mechanic we know carries a machinist hammer, and over the years, most of these have gone titanium to save weight in the tool case. This hammer is 3D printed in hardened 6/4 Titanium with a hollow head that we fill with 125 grams of fine stainless steel and fine tungsten grit, giving it higher impact energy than a solid titanium head, while also eliminating any recoil. The hammer head is hard titanium on one side and medium hard rubber on the other for use on delicate surfaces.
