This is the Salisbury Pewter crab mallet. Each mallet is made of an alloy blend for hardness - pure pewter mallets would be much too soft. Each mallet features a crab etched on one side of the head.
The new mallets are a little larger and heftier than the original.
Approximately 6 1/2" length and 2 1/4" mallet head width. Curved tip on the handle as pictured.
