ABSTRACT OF THE DISCLOSURE A hammer is provided which is useful in solid waste, e.g. metal, shredding operations. The hammer includes a shank member which is adapted to be connected to a supporting shaft, and a replaceable tip member which is subject to wear substantially along its leading and lower portions. Structure is provided for interconnecting the shank and the tip. Such structure comprises a tongue and groove inter- relationship for slidably interconnecting the shank and the tip along a common face. A cooperating keyway pocket and hooked key are provided on the shank and on the tip, with a significant portion of the keyway pocket/hooked key inter- engagement being in the shank. The keyway pocket/hooked key are so interrelated as to tend to retain the tip on the shank during use. Locking structure which is separate and distinct from the interconnecting structure, is provided for locking the tip to the shank. Such locking structure includes a slot passing through the shank and the tip adjacent the trailing edge thereof, the slot being disposed through a side of the tip which is perpendicular to the leading portion of the tip. A wedge is inserted into the slot. Finally means are provided for retaining the wedge in the slot. In this way a tip member is provided which is very easily replaced when worn.
