Sugata
The tachi of the Atsuta shrine measures 75.7 cm in nagasa with a sori of 2.2 cm; it is shinogi-zukuri and mitsu-mune, slender and elegant, with a deep koshizori that bends towards the tip, a lot of funbari and a ko-kissaki, according to Sesko. The other certain signed tachi, of 74.3 cm with a sori of 2.2 cm, is iori-mune, with some machi-okuri.
Jihada
On the Atsuta tachi, a very dense ko-itame with ji-nie. On the second tachi, an extremely dense ko-itame with itame and nagare, ji-nie and chikei: a nashiji-hada.
Hamon
On the Atsuta tachi, a ko-nie suguha with ko-ashi. On the second, a ko-nie suguha-chō with ko-midare, ko-ashi, jō, kinsuji and sunagashi; the nioiguchi is wide and the ha tends towards urumi. An unsigned tachi attributed to him, of 76.6 cm, has a ko-midare with ko-gunome, ko-chōji, ashi and a lot of kinsuji.
Bōshi
Sugu with a small ko-maru-kaeri, almost yakitsume, on the Atsuta tachi; on the second, with hakikake as well.
Nakago and mei
The nakago of the Atsuta tachi is ubu, although the end seems to have been reworked; it tapers strongly, has sujikai-yasurime and ends in kurijiri. The signature, 国友 (Kunitomo), finely chiselled, is placed above the mekugi-ana and towards the back. That of the second tachi is original and has the pheasant-thigh shape (kijimomo).
Signatures that are not his
According to Sesko, Honma says that two tantō signed “Kunitomo” are not Awataguchi work but probably that of another, later Kunitomo of the Yamato tradition. The old books give as his signature the two-character name 藤林 (Fujibayashi or Tōrin), but a tachi so signed failed an old examination; and there is also a ken in the style of the Kikuchi spears that belonged to Naruse Masanari (1567-1625). No one attributes these blades to Awataguchi Kunitomo.
