A Japanese army knife with a copper handle, which reads: Okamura Ningji 0 127 in the 15th year of Showa.

Okamura Ningji was the commander-in-chief of the Japanese North China Dispatching Army, Showa was the title of the Japanese Emperor, and the fifteenth year was Showa. 0 127 is the serial number of Japanese army knife. If it is true, it should be a gift from Okamura Ningji to his officers. But the possibility of imitation is also great. It needs to be identified from the steel and production process, and only professionals can do it.
