Tango no Kami Naomichi was from the Tango no Kami Kanemichi Mon. He was first called Jôuemon Naotsugu. He took the name of Naomichi after his teacher Kanemichi. He worked in the Kyôhô Era around 1716.
This katana is absolutely beautiful and a wonderful example of his work. It has a cutting edge of 27.375 inches or 69.5 cm. The width at the moto-haba is 1.23 inches or 3.1 cm and the saki-haba is 0.78 inches or 2.0 cm. It has a very graceful tori sori measuring 0.57 inches or 1.5 cm. It is ubu with one mekugi-ana.
The jitetsu is a very fine ko-itame hada with masame hada in the shinogi-ji. There are clouds of ji-nie forming tobiyaki in several places. The hamon starts with a typical Osaka Shinto slanted yakidashi and quickly develops into a billowing gunome midare that reaches the shinogi-ji in some areas. The habuchi is absolutely covered in ji-nie. Within the hamon are areas of sunagashi and nijuba. All in all, it is lovely to look at. The boshi is slightly undulating with a ko-maru turn-back and a short kaeri. It is in excellent polish with no flaws and only a couple of very minor recent scratches. There is a very nice two-piece gold foil habaki.
This katana comes with a nice set of koshirae, the tsuka of which shows a good amount of wear to the ito lacing. I love this kind of koshirae because it shows great usage and when you hold it, it is like shaking hands with its former Samurai owner.
This sword comes with Tokubetsu Hozon papers from the NBTHK attesting to the validity of the signature and the quality and condition of the sword.
