Japanese swords were forged according to the height of the first owner. In very old pieces, they are sometimes found modified by cutting from the same blade or in the Nakago to adapt to the appropriate size of the new owner, but it is rare to find them.

This Katana blade has another very rare feature, the initial part of the blade was transformed into Nakago, to shorten but also to modify the curvature (Sori). Hence the unusual shape of the current Nakago.

Katana and Wakizashi condition:

Blades condition is as can be seen in the detailed pictures.
Both blades have undergone a professional cleaning process (not polishing) this action allows them to be kept in their authentic condition of conservation.
The Wakizashi blade shows some superficial and very light stains from old oxidation that has already been stopped and removed.
The same in the Katana blade that also presents a minimum close to invisible defect in the tip. A lack of about 2 cm on the surface and a very tiny chip on the edge. A fold of the old edge that is now under the Habaki so it is not visible.

The edge of both blades is the antique original one and is preserved with the usual razor cut typical of good Japanese swords.
