1 vintage U.S. World War 2 theater knuckle knife.  This WW2 knuckle fighting knife would make an important addition to any collection.

This knife measures 9 1/2" overall.  The blade itself measures 5 9/16".  The knuckle guard is made of heavy steel with skull crusher ridges. 

The scabbard has the Marine Corps symbol scratched into its front.  This can be seen when rotating the sheath under light to get the right angle. 

This U.S. WW2 theater knuckle knife is in good condition.  Everything is nice and tight on this knife with no looseness or wiggle.  The blade is sharp.  This small fighter would definitely do the job.  The sheath is in good condition with some broken stitches, but with all rivets and the keeper strap intact.
