WW2 Japanese Type 30 Early Hook Guard Bayonet Jinsen

This is the standard WW 2 Japanese Type 30 bayonet.

This bayonet was made in Jinsen (now Inchon) in Japanese occupied Korea.

This type of bayonet was issued with all Japanese Arisaka rifles during World War II, regardless of caliber.

The way in which these bayonets were manufactured changed dramatically during the course of the war. There were more than 10 factories making bayonets for the Japanese Army and Navy. This one was made in occupied China at the Mukden Arsenal. 

The blades on all early bayonets, like this one, were left in the white, meaning they were not blued. 

This practice later changed in favor of a blued, less reflective, blade during the war.

All Japanese bayonets made before May 27, 1940 had a hooked cross guard.

After that, in order to conserve metal, the hook guard was eliminated in favor of a straight cross-guard. Some early straight guard bayonets had blades left unblued. Later all blades were blued.
