Vintage CASE pocket knife from an estate sale out of Newark Ohio.  
 
Hard to find SINGLE BLADE "Case XX", "5265 SAB".
 
Made between 1965-1969.  LARGE 5 1/4" KNIFE WHEN CLOSED.  8 7/8" long when fully open.
 
Blade has no dents and is in the usual shape for a knife of its age.  The bolsters are in good shape.  The knife is still nice and strong.  Both handles look like they could be replacements but fit nicely.  No snap left.  Signs of age consistent with an old knife.
