Other Japanese swords

A real (sharp) katana is called a . 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 imitation swords primarily made for decorative reasons, which are generally unsafe for martial arts practice.


Materials and manufacture

which is cheaper and lighter than steel. This use of alloy and a blunt edge also circumvents 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 . The average weight for a real is typically without the scabbard while a typical alloy iaitō is roughly . Some steel iaitō are also constructed and can weigh around for a blade. Some imitation Japanese swords are made in countries other than Japan. They may even be made of folded steel, much like a real

'' until the practitioner's skill is consistent enough to safely use a sharp-edged sword. Some iaidō schools may require a practitioner to start with a ''shinken'' right away, while other schools 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 (

Legislation

The ''Act for Controlling the Possession of Firearms or Swords and Other Such Weapons'',''Act for Controlling the Possession of Firearms or Swords and Other Such Weapons''
, Japanese Ministry of Justice, 1958. (Japanese language) established in Japan in 1958, forbids the possession, production, and importation of any sharpened (or sharpenable) sword. Very few exceptions to this rule exists, but, notably, traditional Japanese swordsmiths are permitted to produce a restricted number of blades over the course of the year. Japanese swordsmiths have a special status, and the weapons they make are considered work of art rather than weapons. (This also explains why nihontō exported outside Japan must go through a declassification process before their exportation.)
