1 antique ca.1920-1940 Case Tested large folding clasp knife.  This old Case knife would make an important addition to any collection. 

This knife measures a large 5 1/2" when closed.  The knife blade itself measures 4 1/4".  The front blade tang is stamped 'CASE  TESTED XX'--with still a third line below it that is largely obscured--I think? I can see '_____90'.  The handle is made of red jigged bone.  The handle's bomb shield reads 'CASE'. 

This antique Case Tested large clasp knife is in fine condition.  The blade has an occasional spot of the lightest of pitting.  The blade is full.  The blade has strong snap, and absolutely no wiggle in the open position.  There is barely one very tight and stable crack in one handle scale--the crack is only barely visible, and is only visible when looking at the spine of the handle.  It is not visible when looking at the flat sides of the handle.
