This Tanto is a good example of Soshu Den style work from the middle Nanbokucho period. Personally, I think this Tanto can be attributed to a second generation Soshu Den blacksmith/ pupil.

Good quality Soshu swords (this applies to all quality swords) is hard to find these days. Nihonto collectors are very fond of Soshu work, good Soshu works are always very exciting and dynamic. This tanto shows many features of Soshu Den, mainly reflected in the Shizu style hamon.

I think this Tanto has a good, 重要 Juyo shinsa, (NBTHK) potential for the future: ATTENTION: this does require more background research. This Tanto is a great addition / step for anyone who wants to have a good Soshu sample, but can’t afford Juyo work yet.

As for koshirae, it will easily get a Hozon certificate, I wouldn’t be surprised if it gets a Tokubetsu Hozon certificate either. Here is a challenge for the new owner.


歴史 History

The name of Naoe-shizu is the general term of the pupils of Shizu Saburo Kaneuji who was a one of Masamune 10 tetsu, (10 sword makers in Masamune-school). Shizu the First, Kaneuji was one of the most skillful swordsmiths of the Masamune School. And Kanetomo, Kanenobu and Kanetsugu were students of Kaneuji. They moved to Naoe from Shizu in Mino Province and started forging swords there. Some of his students gave it the name Naoe Shizu-on.

That is, Kaneuji on and after the second generation, Kanetomo, Kanetsugu, Kanenobu and so on are seemed to correspond to Naoe-Shizu.

The(直江志津派)Naoe shizu school was a Japanese sword school founded by some pupils of Shizu Saburo Kaneeuzi (志津三郎兼氏). The Naoe village(直江村), which was a village in the northern part of Shizu. In the Mino province(美濃).

Famous swordsmiths from the Naoe shizu school are:









Most Naoe Shizu group swords are (unfortunately) are Suriage, O-Suriage cut down, with lost or MEI/signatures as a result.
