In World War II, what level or above of Japanese commanders had command knives?

World War II devils' sabers can be divided into Type 95 army sergeant's sabers, which are manufactured mechanically and mass-produced. They are mainly distributed to people below the sergeant of the Japanese army to wear, and can also be called Cao Changdao, which is the direct maker of evil in the war of aggression. They are called iron bars in Japan.

9 4 Army Saber and 98 Army Saber are sabers worn by junior officers and generals, and there is little difference between them. The 98 Army Saber is only missing the second hanging ring. This kind of saber is used by Japanese intermediate to senior officers, and the classification is on the blade spike. This kind of saber is not uniformly distributed, just like binoculars and pistols, it is purchased by itself.

there is also a rider's saber, which is also used by chariot crew or air force crew.

the navy saber is quite different from the army saber.

Now the Japanese Self-Defense Forces are not equipped with sabers.
