I got mine I think for 150$
it was a mas produced sword by the Japanese government and givin to there regular solders, many had a family sword that they kept, many did not, these are the swords that were givin to those guys, the were not hand pounded, but done on a hammer, they are folded around 4 times, and were not clay heat treated...so do not have a Hamon line.....
they are real.....I am sure there are fakes but they are not gonna fake a plain foot solders sword ( I doubt anyways) if they are gonna fake something it would be an officers sword or something along those lines
also there is a difference some have 2 "rings" some have one I believe the one ring sword is for riding a horse so would be for regular military, and the 2 is for Navy
(if my memory serves me correctly)
send me a link to the one you got
