Among Japanese swords, the regular size of Uchigatana in the Edo period is about 70cm in blade length except at the very beginning and ending period, due to regulations of the Edo Shogunate (swords of more than about 88cm, that is Nodachi or field sword, were banned). |
日本刀のうち、江戸時代の打刀は、江戸幕府の規制(2尺9寸以上の刀すなわち野太刀は禁止された)と、外出中は大小を日常的に帯刀することから、(江戸幕府の)創成期と幕末期を除き、刃渡り2尺3寸(約70cm)程度が定寸である。 |
