Vintage and from an estate sale.  I believe this was made in the 1960's. Beautiful marbled handle.  Marked HAMMER BRAND USA. Condition:  GREAT CONDITION.  Light signs of age only.  Some build up on the blade which should clean off.   See pictures. 2 1/4" including the loop when closed.  Single blade. GREAT CHANCE FOR A COLLECTOR AS IT IS IN FANTASTIC SHAPE, HAS A GREAT LOOK ABOUT IT, AND THIS MODEL IS NEARLY IMPOSSIBLE TO FIND! Location E2
