Funny you mention that http://en.wikipedia.org/wiki/Kiku-ichimonji "The swordsmiths of the Fukuoka School traditionally inscribed only the character "Ichi" (一, one) on the tang as their signature. They further received permission to append the Imperial chrysanthemum crest (菊, kiku) on the tang, thus their swords are known collectively as "Kiku-ichimonji". Kubo you clever dog! You are your naming trope conventions!
