Hello! Sorry, but my English is not so good, so I did not understand the question. Koshirae is, but they are clearly modern and national teams, so I think you should not even pay attention to them. However, as the blade itself. I took this tanto in Japan quite inexpensively.Despite my modest nihonto knowledge, I absolutely had no illusions about this blade and bought it as a modern version. Your opinions
only confirmed my initial views. Of course, not 10-20 dollars, but more expensive, but still, despite modernity (or a piece of old blade), I like this blade in my own way. Thank you all for the answers. Sincerely Alex
