Hi I have purchased a sword from a e bay Web site .a store in Japan.. It is stated as a wakasashi,however the nagasa is 630mm.the tsuka is 250mm long the mei is said to read,Noushu ju Tanikuni Yoshikane.
It also has a sho stamp,
I can not find any clear information on this smith.also I am trying to establish if this is a mass produced sword ,I understand in that you can not help at this stage without sight of the blade.

I own a Hizen kuni yoshikane katana and a Hizen kuni yoshikane wakasashi.
Whilst I have several other swords, ie, sukesada ,masaie,
