Antique pocket knife from an estate sale out of Croton Ohio.
 
THIS IS AN OLD ONE!!  I think this is from the very early 1900's.
 
Marked E.C. Simmons on both tangs.  Made in St. Louis.  Mother of pearl handles.  One blade is a file.  See pictures.
 
2 3/8" long when closed.
 
Wear consistent with a knife from this time period.  The blades have build up but may polish up if wanted.  The two blades and file do open and close.  Snap left on both blades.  One handle has a crack.
 
GREAT PIECE OF HISTORY.  GOOD CHANCE FOR AN ANTIQUE KNIFE COLLECTOR!
