'Indestructible' hammer

The Groz Indestructible Handle hammers were tested with more than 36,000 strikes and didn't fail. The handle is made with spring steel bars that run all the way through the handle and which are locked in the hammer head using a steel plate. A special bonding process ensures that the head does not become loose, while the ergonomically-designed rubber handle reduces vibration and is shock resistant. Redashe says that if the hammer hits an electrical cable, the user is safe from electric shock.

The hammer head is forged from special steel and is induction case hardened to 52 to 56 HRC.
