Iaito (iaitō) rensei (錬成 training), unsharpened katana

Training katana, unsharpened Maru 1045 steel blade, rounded tip


I accompany practitioners as they progress to master the art of Japanese swordplay. I'm not sharpened, so I can train intensively without risk. My traditional frame is sober. My slightly open tsuba makes it easy to draw with the thumb, samurai-style.
Learning the katana involves the use of several types of training weapons, in particular the bokken (wooden sword), the iaïto (unsharpened blade) and the katana (razor-sharp blade). The aim is to master all aspects of martial swordplay: the art of drawing, guiding the blade in space, cutting and sheathing.
"In our school, you have to win, whether you have a long or short weapon. So the length of a sword doesn't matter to us. The will to win with any weapon: that is the Way of our school".
Miyamoto Musashi (1584 - 1645), sword-fighting expert, author of the "Treaty of the Five Wheels" (Gorin-no-sho)

"The sword of life", Yagyu Munenori


The Sword of Life, Heiho Kadensho in Japanese, is one of the three great classics of Japanese fencing, alongside Miyamoto Musashi's The Book of Five Wheels (Gorin-no-sho) and Takuan Soho's The Indomitable Spirit (Fudoshi-shinmyo-roku and Taiaki). While Takuan Soho, as a monk, emphasizes the spiritual aspect of fencing, and Miyamoto Musashi, as a renowned fencer, focuses on the pragmatic, Yagyû Munenori walks the fine line between these two extremes, offering both a philosophical and a practical approach illustrated by concrete examples. For anyone interested in the samurai spirit, The Sword of Life is an indispensable source of knowledge.
