Pictured are a couple of LanCay prototype product improved M9 bayonets, circa 1995. Homer Brett states in his excellent book "The Military Knife & Bayonet", M9 bayonets with these modified webbing systems were submitted to the Army & USMC for evaluation. I was informed by Mr. Brett the reason was twofold for this change. It was determined the exposed sharpening stone on the LanCay scabbard systems led to tearing of uniforms & abrasions by the wearer. In addition, the Fastex belt clip arrangement tended to rattle & make excessive noise.
In response to this, one pattern was provided with a stone covering flap similar in function to the original Phrobis design. The other variant had a more radically redesigned webbing arrangement which not only provided a stone covering flap, but eliminated the Fastex clip.
The first two photos are of the first variant. The bayonet is a early second contract with "LanCay" blade marking, hollow ground blade, & black oxide finish. The last two photos are of the second pattern. The bayonet is also marked "LanCay", has the laser-cut blade, & black oxide finish.
