I purchased this blade for 200$ at an antique fair. The seller is a well known person at these events, and claimed to have bought it from a marine from WWII. I have been around antiques for most of life, and the forge lines made it appear to be made by hand and generally authentic. Later, as I read more about traditional sword making, I discovered the mei on the tang. I was able to translate the first two characters as Tokyo. The third as maybe kore, but I don't speak a word of Japanese. Hopefully the pictures below will provide enough information.
The hamon is incredibly slight and only visible at a certain angle, which made me start to question if the blade is truly Japanese. It has all the imperial dressings of WWII (in the hilt etc). Secondly I read about acid etching and have been fearing my great prize isn't so great. And if it is acid etched and thus fake, why the machine stamped piece where the blade meets the hilt; seems redundant.
Anyways, I would like to know either way, and what the tang/mei translates to.
Thanks for any time and effort spent helping me with this.
