Japanese knife ~ My uncle has a Japanese knife at home, with a total length of 84.5CM and a handle length of 16.5CM. Please help me estimate the market value, preferably in detail!

Let me estimate the value. At present, the bayonets on the cover of March 8th in Japan are generally between 2,000 and 3,000 yuan. Japanese officers' command knives vary according to their positions and ranks. Your knife is probably at least an auxiliary knife or a saber. If the product looks good, the market price should be between 7000-8000 yuan. If the auction can even be sold to 1 ten thousand yuan. You should keep it well and don't let it rust.
