So I believe I have recently come into posessoin of a WW2 Japanese sword, as the arsenal stamp on the tang appears to be the Seki one, though I am a bit unsure. I am a complete novice when it comes to swords in general so my only knowledge is what I have learned in the pat 4 hours or so. I have a gallery on imgur for easier browsing.
