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!
