A multi-purpose metal jigger, ice mallet, and bottle opener from Irvinware. There may have once been a corkscrew concealed in the handle but no longer. The tool measures 5 3/4" long and sits 2 3/4" tall. The front of the graduated 2 oz jigger is marked "Irvin-Ware USA." The piece is in wonderfully aged condition, with evidence of use.
