Katana with grafted tang
This katana blade has a signature of very famous smith. But please study the whole shape of the sword carefully. It is strange. The curvature between the blade and the tang doesn't run properly.
The tang is grafted to the blade.
We found this sword in the collection of our friend some years ago. Of course, he had bought it as genuine sword made by master smith. And then, we have been thinking if we have a way to save the sword. And finally, we decided to buy it from our friend to rescue it.
