Also Buck worked with Phrobis who won the US Army XM9 Bayonet trials. Mickey Finn, who designed the bayonet, realized that there was a potential for a person to get badly injured using the bayonet and scabbard in the wire cutter configuration. He shortened the cutting edge and added the blade stop to help prevent this type of injury from occurring. A small number, maybe 6 or 8, (This one is serialized #1 on the cutter plate) of these bayonets were made to show the Army and were offered to the Army at no additional cost. The Army, in its infinite wisdom, turned it down and insisted on the original design that was tested and won the trials. So this safety feature was never added.
