My red and black frame recalls the cave in which I was forged. The earth's fire still feeds the furnace housed at the bottom of the natural cavity. Carved into the rock, it has been used for centuries by a line of blacksmiths. I'm made from a variety of steels, for better resistance in training and combat. The characteristic waves of my hamon (刃文) run irregularly along my razor-sharp edge to the Kissaki (鋒), my tip, decorating my Bōshi (帽子 part of the temper line visible on the tip of a Japanese blade).
My name was given to me by the samurai master I served. Quick as lightning, powerful as lightning, he would surrender himself during battle, merging with me, extending his spirit and multiplying his supple, confusing movements. His particular style of swordplay led him to create a Koryū (古流 traditional martial arts school). My destiny led me to accompany him to his last breath. Since his death, I've been waiting for the one who can master me with equal ease and efficiency.

When Zen temples became secret samurai dojos

In feudal Japan, certain Zen temples also served as secret training dojos for samurai wishing to combine meditation and swordplay. Supposedly silent and spiritual, these places enabled inner training alongside martial art. The term dōjō originally came from Zen Buddhism before being linked to the martial arts.
The temple Kenchō-jifounded in 1253, was the first Zen center to serve as a formal dojo, combining sacred architecture and martial practice. In Kyoto, the temples Daitoku-ji and Zuisen-jiThe renowned Rinzai schools welcomed warriors in search of mental clarity, swordsmanship and introspection.
The spirit of this training was based on a harmony between meditation (zazen), kata and body control, an alliance that forged warriors who were both wise and precise.

Maintenance kit

Maintenance of a sword or saber is necessary to prevent oxidation (rust). Old oil must be removed and replaced by a film of new oil. The maintenance kit is composed of several elements:
Microfiber cloth: for cleaning, spreading oil and polishing the blade.
Uchiko: a ball of finely ground chalk (chalk powder) wrapped in a ball of cloth. Intended for cleaning the blade's surface, the powder passes through the wrapping when tapped, allowing it to be sprinkled over the blade's steel.
Oil: applied as a thin film, it protects against oxidation.
Mukugi(x 2): pins (bamboo dowels 目釘) that hold the blade and handle (tsuka 柄) together.
Pin driver (Mekugi Nuki): Small brass hammer with a screwed-in pin for removing mekugi.
Maintenance does not require disassembly, but if you need to remove the handle (tsuka 柄), replace the pins.

Figure 1: Cleaning the blade with a microfiber cloth

Figure 2: Tapping the Uchiko on the blade to deposit limestone powder

Handle with care to avoid injury.
1/ Use the microfiber cloth to remove oil from the blade. From the guard (Tsuba 鍔) to the tip (Kissaki 切先), slide the cleaning cloth over the back of the blade (Mune 棟), folding it in half to wrap both sides of the blade.
Lightly squeeze the cloth between thumb and forefinger to surround the blade from above (first illustration).
2/ Once the old oil has been removed, use the uchiko to lightly tap along the blade (second illustration).
3/ Use the cloth to lightly polish the blade and remove the powder, in the same direction as the first step (first illustration).
4/ Apply the oil along each side of the blade with the sprayer (or a very soft brush). The oil should be spread thinly and evenly, without excess (first illustration).
Be sure not to touch the blade before replacing it in its sheath (saya 鞘).
Clean the microfiber cloth with soapy water.

Katanas, swords, daggers and knives are now classified in category D. The purchase and possession of these weapons are unrestricted. In principle, they may not be carried or transported without legitimate reason. If transported, the weapon must not be "directly" usable. It must be securely packed in a case or container, preferably with a padlock or other protective system.
