Good old pocket knife from an estate sale out of Newark Ohio.
 
Two blade.  Marked Robeson USA 622393.  There is some interesting information regarding the Robeson Cutlery Co. online.  You should check it out.
 
No cracks or chips on either scale.  Bolsters are in good shape.  Blades have the usual signs of age.  Great snap at full open, half stop, and full close.  Missing its badge.  SEE PICTURES.
 
2 3/4" long body when closed.  GOOD CHANCE FOR A COLLECTOR.
