THIS IS AN OLD ONE!  Good chance for a collector.
 
"A.W. WADSWORTH & SON".  Made in Germany.  I'm guessing this is from the 1920's or so but please use your best judgement.
 
Beautiful jigged bone handle.
 
THE PERFECT AMOUNT OF AGED PATINA.  Normal signs of age for a knife this age.   Still even has the loop which is usually missing. SNAP LEFT.  Polish or keep the patina.  One small chip in the handle.  SEE PICTURES.
 
MINIATURE at 3/4" including the loop and when closed.
