Good old pocket knife from an estate sale out of Newark Ohio.
 
Hard to find CHALLENGE CUTLERY COMPANY OUT OF BRIDGEPORT CONNECTICUT.  Double blade.  Made in the USA.  Older carbon steel and not stainless steel.
 
MADE BETWEEN 1905-1928.  I believe this is one of the early models so it was probably made closer to 1905.
 
Beautiful and original JIGGED BONE handle material.  SEE PICTURES.
 
The knife still has its badge.  Bolsters are in good shape.  Both blades open and close.  No snap left.  The back handle is chipped.  The blades have signs of age and wear.   SEE PICTURES.
 
3 3/8" long when closed.
 
GOOD CHANCE FOR A COLLECTOR!
