Sledgehammers are the monsters of demolition. They can deliver enough force to pound boulders into dust, but strangely, it doesn't take much to break them in two. When workers miss their target and whack the hammer's handle on debris, called overstriking, the hammerhead can snap off, becoming a dangerous projectile. Wilton guarantees its Bad Ass Sledge Hammers (B.A.S.H.) against breaks, and will cut a $1,000 check to anyone who can destroy one. Depending on the model, up to six steel rods run the length of the handle and affix to a plate inside the head, holding the two parts together. When the hammerhead strikes, the rubber handle disperses the force evenly among the rods, a design that also absorbs vibration.
