Old...antique...and beautiful!  Authentic pocket knife with great patina.  My guess is that this is from the very early 1900's.  Its make is a mystery as I cant fully read its tang stamp.  My guess would be Keen Kutter.
 
No chips in either scale.  One scale is split as seen in pictures.  All blades open and close.  Snap on all blades.   All metal areas have that perfect amount of aged patina as seen in pictures.   SEE PICTURES.
 
3 7/8" long when closed.
 
THIS COULD BE WORTH MUCH MORE THAN I AM ASKING DEPENDING ON THE MAKER.
