Thanks for all information
My sword is surely a traditional hand forged blade, i don't know if made with tamagane or other steel.
Is it possible that the blade was forged by a Kaneyoshi that usually not forge at Inaba and changed the kanji of Toshi in this case?
The blade is very nice. But was on sell on Ebay and there was the photo of torokusho where result the nakago was signed and not mumei. I thick the mei was removed and the yasurime changed.
I've fond this katana at an estate, the horimono is well carved and also the sword seem to be well forged, hamon it's a very good choji with many hataraki,
and also it seems to have also midare utsuri. The nagasa is a bit short only 64,5 with 1,8 of sori. What do you think about it?
