Kuro and Shiro, the hidden code of the samurai

Black and white, much more than a stylistic effect. The black lacquer coating on armor, common from the 14th to the 17th century, protected the metal and reflected the ideal of restraint in bushidō. White, the color of purity and honesty, was seen on cords, tabi, and, in some contexts, on ritual garments. Together, kuro and shiro created a highly visible contrast on the battlefield, which was echoed in the mon (family crests) and sashimono banners. Many clans thus displayed easily identifiable two-color motifs, while swords were given matching scabbards and cords. A black and white katana therefore echoes an ancient visual language that is at once practical, martial, and spiritual.

Maintenance kit

Maintenance of a sword or saber is necessary to prevent oxidation (rust). Used oil must be removed and replaced entirely with a film of new oil. The maintenance kit (御刀手入具) consists of several items&nsbp;:
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.

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.

Legislation

Since September 6, 2013, new legal provisions stemming from the March 6, 2012 law have come into force. These new rules have strengthened criminal penalties against weapons offenders and introduced a new classification.
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.
