Hello ,I just get this sword from a friend of mine .I know blade since a long time and my friend just give it to me because now he return to live Japan .When we were younger we had play a long time with it ahaah we were so stupid ..;
so I just discover mei on the nakago and on a french borad they explain me that it was "Echizen no ju Omi no kami fujiwara Tsuguhiro" . They explain me that it was certainly forged during the kanbun era
the total size is 76,5cm (nakago 15,5)
