Vintage and from an estate sale.  I believe this was made in the 1960's. Beautiful Striped handle.  Marked OKAPI and MADE IN GERMANY. Condition:  GREAT CONDITION.  Light signs of age only.  I dont think the knife was used but a couple times.   See pictures. 3 3/8" including the loop when closed and not including the loop.  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
