Why Titanium, you ask? Titanium hammer heads, at nearly half the weight of steel, have ten times less recoil shock than steel, significantly reducing the risk of Carpal Tunnel Syndrome and other stress related injuries. With a common steel hammers, up to 30% of the kinetic energy created by the user's swing can be lost to recoil vibration, which can be transferred down the handle to the users arm. This energy that is normally lost to recoil with Steel is more efficiently transferred to the nail using a Titanium hammer. This is why the Stiletto Titanium will drive nails as well as the heavier hammers without the extra effort and weight.
