About this sword :  This is a tanto by Nio Kiyosada. There were a few generations of Kiyosada active in the Muromachi period. The NBTHK Hozon paper that accompanies this blade states specifically that this is a work of the late Muromachi period. This corresponds to the Nio Kiyosada listed in Fujishiro as being active around Eiroku (1558-1570).

This sword is a delight to study because it is a text book example of Sue Nio work. The jigane of ko-mokume mixed with masame, clear herakage utsuri(looks like ribbons or steps of a ladder), ko-nie deki hamon and exaggerated iriyama-gata jiri are all classic traits of Sue Nio.

This sword is in nice old polish and has no kizu. The nioi-guchi shows considerable skill. It is consistent in luminosity and width throughout the length of the blade.

This comes with an old shira-saya, silk shira-saya bukuro, old copper habaki and an NBTHK Hozon paper. A signed koto Nio Kiyosada tanto in full polish. Ideal for study and appreciation of Nio works as well as an example of a skillfully made blade of the waring states period.
