Other Japanese swords

A real (sharp) katana is called a shinken (真⁠剣, lit., real sword). In contrast to shinken, iaitō have no cutting edge and are designed for iai/battō practice and are usually unsuited for sword-to-sword contact. These should not be confused with other fake swords, which are primarily made for decorative reasons and generally unsafe for martial arts practice.

Materials and manufacture

Japanese girl practicing iaido. The iaitō shown in this photograph was custom made according to the weight and size of the student. The blade is made of aluminum alloy and it lacks of the exquisite sharpness typical of the traditional steel katanas for the student's safety.

Most iaitō are made of an aluminium-zinc alloy which is cheaper and lighter than steel. This use of alloy and a blunt edge also avoids the Japanese legal restrictions on the manufacture of swords made of ferrous metals. As such, Japanese-made iaitō are intended as practice weapons and are not suited for any type of contact. The best alloy blades are rather faithful reproductions of real swords with authentic weight and shape along with similarly high-quality finish and fittings. Iaitō may even have a mock hamon (刃文, lit., blade pattern, the temper line of a tempered steel blade). The average weight for a real uchigatana (打刀) is typically 1,200 g without the saya (, scabbard) while a typical alloy iaitō is roughly 820 g. Some steel iaitō are also constructed and can weigh around 900–950 g for a 74 cm blade.

Some imitation Japanese swords are made in countries other than Japan. They may even be made of folded steel, much like a real katana, but with a blunt edge. Such weapons would face the same use and ownership restrictions in Japan as genuine swords, and would not be called iaitō in Japan.

Meirin Sangyo Company claims that they were the first to manufacture an iaito.[2] First iaito were made after WW2, to permit people without means to own a real sword, to have a tool for their practice of modern budo. Many swordsmiths located in Seki, Gifu Prefecture, also produce iaitō.

Some dōjō in Japan recommend that only alloy blades be used for practicing iaidō until the practitioner’s skill is consistent enough to safely use a sharp-edged sword, i.e., a nihontō or shinken. Some iaidō schools may require an iaidoka (practitioners of iaido) to start with a shinken right away, while some iaido school prohibit the use of a shinken altogether.

The matching of iaitō length, weight, and balance to the practitioner’s build and strength is of utmost importance to safely and correctly perform the iaidō forms (kata). Due to the repetition involved in the practicing of iaidō: iaitō are often constructed with the balance point of the blade being set further from the blade’s point (kissaki) and closer to the guard (tsuba) than other blades.
