Good old pocket knife from an estate sale out of Newark Ohio.
 
Four blade with can opener.  Marked Camillus New York USA.  I am guessing this is from the 1950's or so.
 
Signs of age consistent with a pocket knife from the 1950's.  No broken blades.  The handle is not cracked or chipped.  The logo plate is still on the unit as well as the loop.  GOOD OLD USA CAMPING KNIFE!
 
Beautiful brown handle.  4 1/4" long including loop.
