M-4 Hard Rubber Grip

M-4 Rubber Grip

The M-4 knife bayonet was developed during WWII for use on the U.S. M-1 Carbine.  This is a WWII M-4 bayonet that has been modified with a hard rubber grip. This was an attempt to find a grip that was more resistant to rot than the WW II leather grip.

It is believed that these modifications were done on Okinawa in the late 1940's or early 1950's, and the bayonets saw use in the Korean War.

Very early M8 scabbard made by the Beckwith Manufacturing Co.  This is a scabbard made for the M-3 combat knife, with the shorter web loop and no wire belt hanger.

M-4 Wood Grip

The M-4 knife bayonet was developed during WWII for use on the U.S. M-1 Carbine.  This is a WWII M-4 bayonet that has been reworked with a one-piece wood grip.  This was an attempt to find a grip that was more resistant to rot than the WW II leather grip.

This example was made by the W. R. Case & Sons Cutlery Co. of Bradford, PA.

It is believed that these modifications were done on Okinawa in the late 1940's or early 1950's, and the bayonets saw use in the Korean War.

Early M8A1 scabbard, made prior to 1955, when the metal tip was added. This example was made in 1953.

The M-4 knife bayonet was developed during WWII for use on the U.S. M-1 Carbine. This example is a post-WWII second production type with the wider crosspiece and black plastic grips.

Made by the Conetta Manufacturing Co., Stamford, CT.  Conetta-made M-4s are fairly common today. According to noted U.S. bayonet authority Gary Cunningham, the existence of Conetta-made M-4 bayonets is somewhat of a mystery. No government records have been discovered to identify when these bayonets were made or how many may have been produced. 

Identity of the scabbard maker, TWB, is not known.

This example was made by the Bren-Dan Manufacturing Co., Stamford, CT.

According to noted U.S. bayonet authority Gary Cunningham, it is possible that Bren-Dan Co. is somehow related to Conetta. Like the Conetta bayonets,  the existence of Bren-Dan made M-4 bayonets is also somewhat of a mystery. No government records have been discovered to identify when these bayonets were made or how many may have been produced.

This M8A1 scabbard, marked “PWH”, was assembled at the Philadelphia Workhouse for the Blind, Philadelphia, PA.
