His designated blades
Two appear in the NBTHK catalogues that can be consulted: the signed wakizashi of the 70th Jūyō session and the attributed katana of the 29th Tokubetsu Jūyō exhibition. The others are cited for him with their session, but have not been seen in a catalogue.

It has not been checked how many different blades these are: some of these designations may be the same blade, promoted later.
In the treatises and the lists
A ranking of kotō quality of unidentified origin places him, in the Enbun era and in Chikuzen, among the 上々作 (jōjō-saku). He does not appear in the Kyōhō meibutsuchō nor in the wazamono lists.
The lists of the NBTHK monthly exhibitions from 1998 to 2024 compiled by Markus Sesko give him two exhibitions, with two blades.
