About this sword :  This is an osuriage mumei katana that has been attributed by the NBTHK to the Chiyozuru school. This school was active from the late Nambokucho period through the mid-Muromachi period. The founder of this school was Chiyozuru Kuniyasu. He was a from the Nakajima-Rai group and moved to Echizen. This was the origin of the Echizen Rai school. In his young days, Kuniyasu's name was Chiyozurumaru. The literal meaning of this is "one thousand year old crane". Due to this positive meaning of a wish for long life, Chiyozuru blades were often selected for gifts in old days of Japan.

This blade is in good old polish and has no kizu. There are some minor surface rubs from the saya. The sugata is elegant and this is complimented by its long nagasa of over 28 inches. This is a healthy Echizen Rai with no sumigane, which can be seen in works of the school that have been polished many times. There are two kiri-komi on the mune of this blade. These were caused by the use of this blade in battle to block a blow. It is an aspect of appreciation that conveys how well made the blade is for its intended purpose and makes us wonder what stories this old solider could have to tell.

A katana koshirae accompanies this sword. It has an old saya with banded urushi in good condition. The fuchi kashira are shakudo with gold / silver inlay and signed Yasuchika. This may be a later generation Yasuchika. The workmanship is typical of the group. The menuki are a flute and floral motif. The tsuba is a later Higo example. The habaki is sliver and finished in the falling rain style. There is no shira-saya or bag.

This is a lovely koto katana that is a joy to study. It is quite long and has the graceful elegance that so many of us admire in old blades. It is healthy and has no kizu. A great opportunity to own a full mounted and NBTHK papered Chiyozuru katana.
