U.S. M3 Combat Knife.  K.I. maker coded (Kinfolk).  Very good condition.  7" blade has a good finish with wear and age and one small chip on the top edge near the tip.  11 1/2" overall length.  Maker coded on the underside of the guard.  Metal fittings are good as is the leather wrapped handle.  Ordnance mark on the pommel.  Comes with a U.S. M8 B.M. Co. scabbard that's in great shape.  Nice piece of U.S. military history.
