Sacred Earth Katana (聖地, Seichi), sharpened blade 1095, genuine hamon, brown braiding #Terressens

Sacred Earth Katana (聖地, Seichi), sharpened blade 1095, genuine hamon, brown braiding

Sharp Katana, extra-hard steel (1095), genuine hardening line (hamon 刃文), with black scabbard (saya 鞘), delivered in a composite wood case containing a maintenance kit, lacquered stand and protective fabric cover


Carried by my samurai master, I crisscrossed the land to the point where my new mount bears the trace of it. The brown rope is now the symbol of my name, Seishi (聖地 Sacred Earth). It's a fitting tribute, as my birth also took place in the heart of the earth. The ore from which I came, Satetsu (砂鉄), produced Tamahagane (玉鋼). It is from this noble fraction of steel, which the traditional furnace, the Tatara (鑪), produces after five days, that I am made. This is my birth, my history.
But what I'm most proud of is the true tempering line that adorns my blanks. Indeed, it's discreet, but a sign of the metallurgical expertise of those to whom I owe my life. A layer of clay protected my back (棟 Mune) during heat treatment. The result is a wire that's very strong but still flexible. The ripples along my cutting edge (刃 Ha) form a unique signature, the Hamon (刃文).
I come from the earth. I protect it without concession.

Japanese sword metallurgy (choosing the right katana, 1ʳᵉ part)

Various criteria can play a part in the choice of a katana (刀). Its use in martial or sporting practice, as well as the level of the practitioner, influence it considerably. Its weight, point of balance, construction (materials and mechanical characteristics) are all criteria to be taken into consideration when choosing your Japanese sword or Shinken (真剣, contemporary katana).

History & Symbol

Japanese crane (Grus japonensis), symbol of longevity in Japan (photo: BS Thurner Hof, Wikipedia)

The Japanese crane (Tsuru 鶴)

In Japan, the crane is a symbol of longevity. Legend has it that it lives to be 1,000 years old. This animal is present in iconography (as a motif on Japanese kimonos, fabrics and papers) and folklore. The tale "Tsuru no Ongaeshi" (鶴の恩返し), for example, tells of a crane rewarding an elderly couple by weaving marvelous fabrics with its feathers. The crane thus has a reputation for granting favors.

In origami, cranes are particularly appreciated. The legend of the 1000 cranes (Senbazuru or Zenbazuru 千羽鶴, せんばづる) claims that if you make 1000 origami cranes in a year, held together by a tie, you'll have your wishes fulfilled (for yourself or someone else). For the wish to come true, you have to make each crane, saying a prayer when it's finished.

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.

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.

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.

Buy Katana "Terre Sacré" at Terressens
Personally, I had a hard time choosing a site on which to buy my first Katana. I decided to buy from Terressens, as it's a French store.
Frankly, I'm not disappointed with my purchase, with engraving to boot. Communication with the engraving department was top-notch, and I received my item in barely 1 week (engraving included). The katana seems well made and sharp.
Great stuff, I highly recommend it for your katana purchases.
