I am looking at a Soshu blade that is pointing toward Hasebe. That is, hitatsura, O-itame with a strong masame in the yakiba and toward the mune.
The problem is, it is a 19.5" wakizashi with a Funa-Gata Nakago that appears Ubu and Shinto. The only way around this is if the blade is O-suriage, which there is indications it might be. For example, the hamon runs all the way to the rust and, even more striking, the shinny area of the blade runs under the kiri file marks of the nakago approximately one inch.
My question is, are there O-suriage blades where they have gone to the trouble to totally reshape the Nakago to resemble the original ... or that is consistent with the Nakago of the representative school?
