This maker is the 6th generation Tango no Kami Kanemichi but he used the names of Naonori and later Naomichi. He was born in Osaka and became a student of Hamabe Toshinori and then used the mei of Naonori. In 1791, he changed his name to Naomichi. He also worked in Edo and then Owari in his last days. Sometimes, he added "kaminariyoke" to his mei which means "warding off lightning". He is ranked as Chu-Jo Saku by Fujishiro and given 4.5 million yen in the Tokotaikan.
This is an o-kozuka dates to Kansei (1789 1801)- the time this smith was using the Naonori mei. The nagasa is 21.0cm, mihaba is 1.95cm and the kasane is 4mm. The hamon in a dynamic gunome midare in nioi with ko-nie. Ji-nie and chikei can be seen in the hada as well as tobiyaki.
This comes with a shira-saya and storage bag. It is also accompanied by an NBTHK Hozon paper that states this is a work fron the Kanesei nengo in parenthesis below the record of the mei. A nice o-kozuka by a well regarded shin-shinto smith.
