French nihonto

yes my photos are bad but with good light and with the naked eye it looks good. you have an idea for the period?

thanks paul. yes sorry for not having said too much, I did not want to influence anything. I share your opinion on koshi-zori. i found a enju school blade dated kamakura. the hamon is very similar, the color of steel and also similar, for the hada I'm not sure. Maybe a lead. the blade in question:

Hello nihonto lovers, I am French and I have been following your conversations for several years and now I am getting started. I have always had doubts about identifying with this blade, it has always given me a problem identifying suriage. What do you think? The blade is far from perfect, with a very old polish. But despite the suriage she kept a good balance, which is not always the case, she has a fairly large grain, not unpleasant. So in your opinion? thanks Cutting edge : 57,6cm Nakago tang length : 11,4cm Whole blade length : 69cm Moto-haba : 26mm Saki-haba : 15mm Moto-gasane : 5mm Saki-gasane : 3mm Sori curve : 14mm Kissaki point : 21 mm
