FACTORY CASTOFF?  Interesting mystery.  One of the scales has a crack by one of the pins.  The main blade doesnt have the factory "Everlastingly Sharp" etching.  As a result the factory X'd out the tang stamp and never etched the blade?  Please use your best judgement.
 
Made by Schrade in NY USA.  1983  "Everlastingly Sharp" muskrat.
 
Genuine RED bone scales.
 
Some light signs of age and use.  Some build up on bolsters which may clean off.  Great shape and a clean knife.  SEE PICTURES.
 
3 7/8" when closed.  Double blade.
 
GREAT CHANCE FOR A COLLECTOR!
