Sharp katana, Soshu Kitae forge (steels 1045 / 1060 / 1095), genuine hardening line (hamon 刃文), hand sharpening, with scabbard (saya 鞘) dark red inlay effect, delivered in a wooden box containing a maintenance kit, a lacquered stand and a protective cloth cover


I am a symbol of fulfillment. My scabbard (鞘 saya) is decorated with a bamboo branch that runs along the curve of the blade. It also features two hummingbirds. Bamboo, symbol of wood among the 5 elements of Feng Shui (Wood, Fire, Earth, Metal and Water), represents an ascending energy. It's linked to creativity and fulfillment.
The hummingbird exists only in America, but being the world's smallest bird, it is often depicted in Japanese paintings and illustrations. A symbol of love, birds also represent freedom, inspiration and opportunity.
So the blacksmith who brought me to life after many hours of toil, forging, clay heat-treating and hand-sharpening also wanted my frame to represent what we all aspire to: fulfillment.

"The Spirit of Bamboo in Japan Paperback, Dominique Buisson


In Japan, bamboo is considered a wonderful material. Because it grows everywhere, grows quickly and can be worked like wood, it has been part of Japanese daily life since time immemorial. From architecture and furniture to an infinite range of everyday utilitarian objects, up to 400 uses have been identified for bamboo. If bamboo is Japan's all-purpose plant, it also has the remarkable quality of being a medium for the mind. The painter defines it as the perfect symbol of beauty; the gardener shapes it into hedges and fences to sacralize spaces; the warrior draws from it the philosophy of "the bow and the arrow"; the tea master, the rustic simplicity of his art. This book shows how this exceptional plant, whose smooth, slender culms are likened by the Japanese to the ribs of a celestial cathedral, has shaped the imagination, aesthetics and everyday experience of an entire people.

Maintenance kit

Maintenance kit for katana (shinken) blade #Terressens

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 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.

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.
