Notes

There exists an origami for this blade issued by Nihon ToKen Hozon Kai, issued Heisei 7th year (1995), stating that the blade is the work of Sekishu (Iwami) Naotsuna den. Hawley, 'Japanese Swordsmiths', lists 5 smiths using that name in that province whose dates range from 1334 to 1688. Deryk Ingham’s initial research suggested that the blade could be Shodai (working period thought to be in the 1330s). Subsequent opinions and study have revised this slightly, assessing the probable date of the sword as Eiwa period, 1375-1379, suggesting that this blade is possibly by the second generation.
