Your memory must be fuzzy. You just referred to Miyamoto Musashi as "lesser known" :-)

https://en.m.wikipedia.org/wiki/Miyamoto_Musashi

"Musashi, as he was often simply known, became renowned through stories of his unique double-bladed swordsmanship and undefeated record in his 61 duels (next is 33 by Itō Ittōsai)."
