Good old pocket knife from an estate sale out of Newark Ohio.
 
I believe this was made between 1940-1964.  Marked Robeson Shuredge.
 
Both scales have no cracks or chips...one has a small hole.  All bolsters are in good shape.  No snap left.   Some signs of age on on blades and scales.  One missing liner piece.  SEE PICTURES.
 
Black delrin or bakelite scales.  
 
3 1/2" long body when closed.  GOOD CHANCE FOR A COLLECTOR.
