Abstract: A hammer tip for releasable integration with a hammer, used in a size reducing machine. The hammer tip is separated into a production block with a top working edge and a spacer block. The production block and spacer block utilize a saddle back attachment to the hammer. The production block is further supported with a lock ledge integration to the spacer block. The spacer block further includes a pair of wings extending outwardly from the left and right sides, and forwardly from the front side, of the spacer block to form additional cutting edges. The wings provide for additional sizing of the material being ground and help move (or push or carry) more material through the grates of the size reducing machine in the same amount of time as compared to spacer blocks without wings. This increased throughput improves efficiency of the size reducing machine.
