I sell and have seen a lot of knives and this is one of my favorites.  The natural handle material is BEAUTIFUL.  Natural smooth bone and not synthetic in any way.  The handle material is semi-transparent.  THIS IS AN OLD ONE!  Looks to be pre WW2.
 
THE ONLY ONE WITH THIS HANDLE MATERIAL CURRENTLY LISTED OR THAT HAS RECENTLY SOLD ON THIS SITE!!
 
Four blade with can opener.  Marked Camillus Cutlery Co New York USA.
 
Signs of age consistent with an older pocket knife.  No broken blades.  The handle is not cracked or chipped.  The logo plate is still on the unit as well as the loop.  Not much snap left.  GOOD OLD USA CAMPING KNIFE!
 
3 5/8" long when closed.
