These are genuine, authentic blades issued by the U.S. military, NOT A REPRODUCTION. ONLY 325,000 PRODUCED. This is the BUCK M9 PHROBIS III Military Blade/Bayonet with sheath included. It is 0.235" thick stainless steel with a saw tooth top edge. Due to "overwhelming user preference in all categories," the M-9 multi-purpose bayonet designed by Phrobis III Ltd., and manufactured by Buck Knives has been selected by the U.S. Army to succeed the old M-7 bayonet. The Phrobis entry passed all Army tests and was judged to be the best multi-purpose system-bayonet, field knife, combat knife, wire cutter and "general" knife-by the soldiers who field tested the bayonets entered in the bayonet competition. Has an ergonomic textured thermoplastic nylon handle and scabbard with wire cutter. The M-9 has a hole in the blade allowing the bayonet to be attached to the scabbard for use as a scissors-like wire cutter. The scabbard also contains a whetstone for in-the-field sharpening.
