I bought this sword as a production of this swordmaker "X" and from this Muromachi era and as a "suriage" sword, the certificate says all this, the blade (nakago) suggests an "o-suriage" (long cut).
It doesn't bother me at all to think of a craftsman who was inspired by previous blades nor that in a later era (I think Edo) the blade was shortened to make it suitable for the fashions and styles of the time.
I also think that if the muromachi is famous for blades produced "on a large scale" and of poor quality, this reconstruction of my sword may instead suggest a not so poor product, for the time both for the name of the alleged creator and for the inspiration of the sword as a style-project.
The observation of the presence of only one hole on the tang led us to the dissertations on suriage.
There are some scratches on the polish as we noticed at the beginning, perhaps from "rubbing", otherwise it's fine for the price
Stay tuned for the fotos
