Thumbnail image of modified Type 30 bayonet scabbardThumbnail image of modified Type 30 bayonet scabbardThumbnail image of modified Type 30 bayonet scabbardThumbnail image of modified Type 30 bayonet scabbardThumbnail image of modified Type 30 bayonet scabbard Modified Type 30 Scabbard Modified Japanese Type 30 bayonet scabbard used by South Korea's forces during the Korean War. The scabbard is painted olive green and a specially-fabricated web belt hanger is attached to the frog loop by a steel fastener.

During 1951–52, Japanese Type 99 rifles and Type 30 bayonets were modified at a former Japanese Army Arsenal for use by the Korean Constabulary and the Korean Augmentation to the U.S. Army (KATUSA) program. Modifications included rechambering the rifles to fire the .30–06 cartridge and adding a belt hanger to the Type 30 bayonet scabbard, enabling its use with U.S. M1910 web equipment.

The KATUSA program was conceptualized by Gen. MacArthur as a way to provide U.S. Army combat units with knowledge of the geography and to enable U.S. units to more effectively distinguish between allied vs. enemy Korean troops. The program involved recruiting Korean men with at least some English language proficiency and imbedding them in U.S. Army combat units. Over 40,000 Korean troops served in the KATUSA forces during the Korean War. The KATUSA program was very successful. It is still operating in South Korea today and the concepts upon which the KATUSA program is based are evident in U.S. combat operations in the Middle East.

n/a n/a n/a Body: "192"
M5 Knife bayonet for use on the caliber .30–06 U.S. M1 Garand rifle.

The USA provided 51,338 M1 rifles to Korea between 1950 and 1963 under the Military Assistance Program.

This is a Second World War U.S. M1 bayonet, whose blade has been shortened and slimmed to resemble the M4 bayonet blade. Korea used the designation "M5" for this bayonet, even though it was not a U.S. M5 bayonet. To avoid logistical confusion, the U.S. created a Federal Stock Number (FSN) for this bayonet (1005-726-6556), even though it did not exist in U.S. military stores.

The scabbard is a a shortened U.S. M7 scabbard. The fiberglass body is covered in a thin soft steel sheathing and a thick coat of olive green paint.

These bayonets are also found in the U.S. M8A1 scabbard or the Korean K–M8A1 scabbard shown below.

An exact clone of the U.S. M7 bayonet and M8A1 Scabbard. Bayonet has a factory edge like U.S. M7s, but not as finely executed.

There are several Tong Yang corporations in So. Korea. I hadn't been able to determine which firm produced the scabbard. However, Dutch collector Jeffrey De Leur’s research confirmed the maker as Tong Yang Tech. Industries Co. Ltd. in Choongbuk, So. Korea. Tong Yang Tech. Industries was formed in 1957 to produce goods for the So. Korean Army.
