This is a vintage Art Deco Design Sterling Silver Bottle Opener.  The handle is sterling silver and the opener is stainless steel.  It has been professionally polished, but has some slight marks on the handle.  It will make a great addition to any bar.  The handle is weighted so a gram weight is irrelevant.  The length is 6 1/2" long.  The opener is marked stainless steel and the handle is stamped Sterling.
