I just got this Wakizashi this week. Better then what I thought, very heavy and thick and robust meaty blade, beautiful black rust on the Nakago. And to make it better, it has a great O-Kissaki tip on it. I could not be more happier with it. It's going to need a Shirasaya, and not sure if I want to send it off for a full polish, it has plenty of polish for me, beautiful Hamon, and great Hada. Really nicely detailed Habaki also. The blade is Mumei, unsigned, and I believe it to be from the Shinto Era. The total length is 20.5 inches total. The width of the blade is slightly over 3.5 inches, close to 4 inches. I just need the tag that is glued on the Tsuka translated now. Of course I had to properly clean it. An very knowledgeable person said the following about it; His Impression is that this may be a Sue-koto sword rather than Shinto. The blade has a wide mihaba and a pronounced saki-zori. There are pools of mokume in the middle of the ji. I would guess that this a sword that is related to Soshu, such as Tsunahiro. The mokume placement is also a trait of Shitahara; Thanks..
