ABSTRACT:
A hammer cast in a sand mold of one piece including a head and a handle. The material of which it is cast is a magnesium aluminum alloy. Both the handle and head have axes which are normal to each other and a rod is mounted in the handle extending the length of the handle and completely through the head with the rod being essentially coaxial with the handle. Serrations formed in the rod enhance the anchoring of the alloy and the serrations are formed on the rod such that the plane passing through the axes of the handle and head does not pass through the serrations. The handle merges in a smooth curve into the head of the hammer, the merging surface defining a smooth concave exterior surface on the handle with no sharp angular edges.
