The Japanese bayonets are often constructed with a catch that secures
the bayonet in the scabbard. A one-piece catch and spring extends the
entire length of the hilt to the pommel, secured by a single screw. The
catch projects upward and protrudes through a hole in the cross guard.
The blade of the bayonet is bright and has flat fullers.The primary kind of bayonet used on Japanese rifles in World War II was the Type 30, introduced in 1897. The average length of these bayonets was about 20 inches and were produced in 18 distinct manufacturing patterns. They bore serial numbers assigned independently from those assigned to the rifles.
