Artisan Nagaaritoshi (長有俊)
Era period (traditionally placed around the Kenmu era)
Explanation Aritoshi is transmitted as a swordsmith of the lineage in Yamato. Among works associated with this name, there are examples bearing a two-character signature, and others that are signed with the three characters “Naga Aritoshi” (長有俊). In the former group, an inscription dated Einin 6 (1298) is seen. According to the prevailing view, the three-character signature “Naga Aritoshi” represents the second generation of Aritoshi, working around the Kenmu era, and is said to be an abbreviated form of “Chōbei no Jō Aritoshi.”
This shows tightly forged with a slight admixture of flowing , and an extremely fine, thickly applied , with fine appearing frequently. The is fundamentally -toned with intermingled and ; along the appear , , and , while the is thickly applied and the is bright and clear. These features of both and conspicuously display the characteristic traits associated with Naga Aritoshi, and thus the attribution is readily affirmed.

In this work, even among pieces attributed to Naga Aritoshi, the is especially strong: thickly congealed forms that appears repeatedly at the with splendid activity. The also shines with a thoroughly bright, clear tone, and the workmanship is outstanding.
