Type 30 bayonet

The was a bayonet designed for the Imperial Japanese Army to be used with the Arisaka Type 30 Rifle and was later used on the Type 38 and Type 99 rifles and Types 96 and 99 light machine guns. Some 8.4 million were produced, and it remained in front-line use from the Russo-Japanese War to the end of World War II. All Japanese infantrymen were issued with the Type 30, whether they were armed with a rifle or pistol, or even if they were unarmed.
Description.
The Type 30 Bayonet was a single-edged sword bayonet with a blade and an overall length of with a weight of approximately 700 grams. The Type 30 bayonet is also known as the “Pattern 1897 bayonet”. Early Type 30 bayonets usually sported a J-shaped hooked quillion guard which was designed to catch and trap the enemy's blade. By 1942 the quillon was eliminated to save materials and decrease production time, leaving only a straight guard. Type 30 scabbards went from metal (pre-1942), to vulcanized fibre (1942-43), and finally to wood or bamboo (1944-45). Scabbards were usually painted black and called a burdock sword (gobo ken) as it looked like a burdock, a vegetable.
The design was intended to give the average Japanese infantryman a long enough reach to pierce the abdomen of a cavalryman. However, the design had a number of drawbacks, some caused by the poor quality of forgings used, which tended to rust quickly and not hold an edge, and to break when bent.
The weapon was manufactured from 1897 to 1945 at a number of locations, including the Kokura Arsenal, Koishikawa Arsenal (Tokyo) and Nagoya Arsenal, as well as under contract by private manufacturers including Matsushita, Toyoda Automatic Loom and others.
