Katana by the first Kawachi no Kami Kunisuke, signed 河内守藤原国助 (Kawachi no Kami Fujiwara Kunisuke). According to the Jūyō paper's description, Kunisuke was the youngest pupil of the Horikawa school, settled in Ōsaka and was a pioneer of smithing in that city, with a strong influence on later smiths. The blade is shinogi-zukuri with an iori-mune, 76.65 cm in nagasa and 1.4 cm in sori, with a motohaba of 3.0 cm and a sakihaba of 2.1 cm. The original seller describes a tightly forged ko-itame jigane mixed with mokume, thick ji-nie and fine chikei; a wide hamon of notare with gunome, chōji and togari-ba, with nie, yubashiri, tobiyaki, ashi, kinsuji and sunagashi; and a straight bōshi turning back deeply in ko-maru with hakikake. The photographs show the broad undulation of the hamon along the whole blade. The tang is ubu, with ō-sujichigai yasurime, a kurijiri tip and a single mekugi-ana, as the photographs confirm. It was designated Jūyō Tōken at the 38th NBTHK session (30 October 1992), and the paper appears in the photographs together with its oshigata. According to the original seller, it is published in the Shintō-shū. It is kept in shirasaya, without koshirae.
