A small Ichimonji school group of swordsmiths who live at Iwato-sô, Bizen from end of Kamakura period, they were called Iwato-Ichimonji "岩戸一文字". In the swordsmith directory, it mentions Yoshiuji "吉氏", but no evidential swords could not be found. So that it was considered that Yoshiie "吉家" was a representing swordsmith. Since there was a sword of Yoshiie "吉家" which has signature "一 備州岩戸住地頭左兵衛尉源吉家" with Gentoku "元徳" the name of an era, he was a lord of manor Bizen Iwato-o-shô "岩戸荘". This sword forging pattern comes to surface a little. Then pale utsuri comes to appear. The kashiras of chô-ji hamon line up evenly. Midare hamon which has a few differences of height. Those characteristics identify the sword of Iwato Ichimonji "岩戸一文字".
