Iaito Minosaka Satsuma Koshirae

The blade length is measured in the Japanese traditional unit called Shaku. One Shaku equals 30.3 cm, or roughly 1 feet (0.994 Ft.). Its sub-unit is the "Sun". There are ten "Sun" in one "Shaku", so 5 Sun can also be written 0.5 Shaku. Please note that a blade length does not include the Habaki (see pictures), but is measured in a straight line from the tip (Kissaki) to what is called the Munemachi (base of the blade), hidden under and partly covered by the Habaki. Light and standard blades are available for lengths up to 2.55 Shaku and thick/heavy blades are available for lengths up to 2.70 Shaku, owing to the alloy’s resistance. Wakizashi are available from 1.30 to 1.50 Shaku.

The Satsuma Koshirae is the only Iaito that can be manufactured up to 3 shaku. The blade being specifically designed and manufactured for extra long blade, it is not possible to manufacture it under 2. 80 shaku.

The blade length depends on your height, on your arms length and on the school in which you practice. The size table below is the official recommendation of the Japanese Iaido Federation. Women are advised to use a blade one size shorter than that of men of the same height. We also recommend for people who are not specialists (Aikidoka for example) to use a blade a size shorter than the recommendation, because it will make the sword unsheathing/sheathing easier.
Blade length is of course related to the Saya length, but note that for a same blade length, the Saya length can slightly vary.

Please also make sure to consult your teacher to check that the size table below is applicable to your school.

Please note that the size recommendation does not apply to Wakizashi as the Iaido federation does not provide such recommendations. However, we do recommend avoiding too long blades for small practitioners

The habaki is the piece of metal circling the base of the blade. It has two main purposes: locking the tsuba in its place and holding the sword into the Saya.
Unlike the Shinken Habaki which can be very expensive, the Iaito Habaki are standardized and gently forced into place. This means removing or changing the Habaki on an Iaito blade is not recommended.
Habaki are made of brass and are available in three different designs: Muji, Shonai, and Yujo, and in 3 different finishes: black (oxidized), gold plated, and silver plated. Please note that due to the oxidation process, it is not possible to blacken the Shonai design.

The Seppa are washers used in front and behind the tsuba to tighten the fittings, made of copper or brass. They are compulsory to keep the Tsuba safely in place.
They are available in brass, copper, black (oxidized), gold-plated brass, and silver-plated brass.

The Tsuba is the sword's guard. It has the function of protecting the hand from the opponent's blade but also from having one's hand sliding onto the blade during Tsuki (thrust) techniques.
However, it has two other qualities: aesthetics and balance adjustment. During the Edo period, the Tsuba turned progressively into a decorative ornament. It was often generously well made, giving every sword a personal and particular touch.

There can be one or two holes on the sides of the Tsuba. They were used to unsheathe the Kogatana (small knife) or Kogai (hairpin) that were fitted inside the sides of the Saya. Tsuba used to be made by entire dynasties of craftsmen who only specialized in that particular field; they have almost vanished in the present time.

The average weight of a standard Tsuba is 120 g.
A heavy Tsuba (> 120 g) will tend to shift the balance downwards the handle, making the Iaito easier to handle whereas a light Tsuba (< 120 g) will push the balance towards the Kissaki, the tip of the blade. The latter is recommended if you decide to focus on cutting training. You will find below some pictures of all our Tsuba but also details on size, material, and weight.

The Sukashi series, from TM031 to TM036 is a special series of widely opened Tsuba (called Sukashi). Made of blackened iron, they are coated by hand with a traditional lacquer.

Please note that the pictures above only display the front side of the Tsuba. You can find pictures of the reverse of each Tsuba on the dedicated product page.

The Tsukaito has two main goals: it serves as a grip and it holds the Tsuka tightly. A tightly wrapped Tsuka is extremely important for security.

Cotton allows better absorption of the sweat but it is less durable than silk and leather. It is the standard option for most Iaito.
Silk feels a little harder and is sometimes not recommended for beginners. However, it has a significantly longer lifespan.
Sweat is not really absorbed by Leather but this latter offers an excellent grip and it is the most durable material. Leather is available in standard and suede version (napped finish). The latter has a slightly better grip but it is slightly less durable.

Please note that those materials are made traditionally - they are not mass-produced. Therefore, colors can slightly vary depending on the batch.
In general, the Tsukaito is of the same color as the Sageo to keep the fitting harmonious, but this is not compulsory; you can select two different colors if you like.

The Samekawa or "shark skin" is the part under the Tsukaito. Shark hunting is no longer practiced nowadays; therefore, despite the name “samekawa”, it’s actually stingray skin which is used. Its main goal is to keep the Tsukaito into place and to reinforce the Tsuka structure. The Same is sanded and polished in order to produce a durable superior-quality type of leather.
On live blades (Shinken) mounts, the Same is a "maki same", which wraps the Tsuka wood. However, for cost reasons, the Iaito Tsuka is made with two rectangular pieces of Same inlaid in the Tsuka. This is called Tanzaku-same.
The "Makisame" is a large piece of stingray skin which wraps the Tsuka. It makes the Tsuka slightly bigger and it significantly strengthens it, which improves its grip and its lifetime. The Makisame is made the same way Shinken Same are made.

Please note that we also offer a plastic Same option for customers concerned about animal protection. The plastic Same is only available as a "Tanzaku Same only" (Makisame is not possible).

The Tsukamaki is the way the tsukaito (cord) is wrapped around the Tsuka. The Hinerimaki is the standard wrapping, known by all practitioners.
The Hiramaki is a very specific wrapping that enables to make the centre of the Tsuka flat. This is a popular wrapping in Iai schools which use an important number of single-handed techniques/moves.  
In order to hold the Menuki correctly, the cord goes over the Menuki on each side (which may significantly hide the Menuki if it’s a small one).  Please note that we do not recommend this wrap for intensive practice as it is less durable than the standard Hinerimaki wrap.
Finally, the Katatemaki style is more designed for decoration than practice because it doesn't hold as well as the other wrappings. It is however proved that it was the wrapping used by the famous Samurai Akechi Mitsuhide. Given that the side parts of the Tsuka are left naked, this wrapping is only available with the Makisame option.

In option, we offer to put 2 Mekugi (peg) in the Tsuka. This may reassure you as 2 Mekugi make you feel safer. However, from the craftsmen's point of view, since Iaito are very rarely taken apart, this option is unnecessary. This option is not available for the Hiramaki.

The Menuki are ornaments on the Tsuka to insert into the handle so as to fit into the palm for grip. Originally, they are meant to distract the eyes from the Mekugi (peg). It is generally placed under the wrapping, but they may also appear on the wrapping, especially with a Ikkan-maki or Hira-maki wrapping style. Several thousands of designs have been created over the centuries. It is considered as jewellery and as such it has inspired many craftsmen.

The Menuki are usually located on the top of the left side (omote) and at the bottom on the right side (ura). We also offer two other possibilities: center both Menuki (on each side), or reverse positions (also called Sakasa Menuki) which will place the Menuki under your palms rather than under your fingers.

The Kurikata is the piece placed 8 cm from the Koiguchi (Saya hole) on the Omote side of the Saya, used to interlock the Sageo.

The Kurikata is usually placed 8 cm from the Koiguchi. Depending on your body type and on the school you practice, you may want to move away the Kurikata a little. You can set the position up to 20 cm from the Koiguchi, but it shouldn't be farther than 12 to 15 cm. This option increases the production time to about 5 to 6 weeks.

The Shitodome is a small piece of brass, gold or silver plated, inserted in the Kurikata (the hole in which the Sageo goes). The Shitodome is purely decorative.
Shitodome can only be fitted on standard Kurikata. Selecting a Shitodome will change any special Kurikata (ie. Dotanuki) to a standard Kurikata.

Please note that Shitodome only fit on regular Kurikata. If you select a Shitodome for a Dotanuki model with a metal Kurikata, it will be replaced by a standard Kurikata.

The Sageo, the twisted lace which is provided on the Saya Kurikata, has two main purposes: it is tied to the Obi (belt) to prevent the Saya from falling when the sword is carried by its owner, and it has an ornamental purpose when the sword is displayed. Some Koryu also teach how to use the Sageo as a weapon or to tie an opponent's hands (Hojujutsu). It is also said that the lace serves as a spiritual bond between the samurai and the sword.

Iaito Sageo are usually made of lower quality synthetic silk (not offered here) cotton or silk.
Cotton Sageo are available in plain colors as well as in check patterns.
Silk Sageo are only available in plain colors. Silk Sageo are woven more tightly than cotton but are also thinner, which gives them a harder touch than the cotton ones.
Please note that for the Black Silk Sageo, the former weaving (Kakucho) has been replaced by a new one (Shigeuchi), giving the sageo a thicker look.
The colors may vary slightly depending on batches due to the traditional dyeing techniques.

The standard Sageo length is 210 cm. Only the silk Sageo is available in 240 cm.

All Iaito are delivered with the Sageo tied with a knot called "Ronin" knot, the way most craftsmen do. It is the most common knot for decorative purposes.
