context_page_description: A katana is a Japanese sword characterized by a curved, single-edged blade with a circular or squared guard and long grip to accommodate two hands. It was used by the samurai of ancient and feudal Japan.
context_section_description: Between 1945 and 1953, sword manufacture and sword-related martial arts were banned in Japan. Many swords were confiscated and destroyed, and swordsmiths were not able to make a living. Since 1953, Japanese swordsmiths have been allowed to work, but with severe restrictions: swordsmiths must be licensed and serve a five-year apprenticeship, and only licensed swordsmiths are allowed to produce Japanese swords (nihonto), only two longswords per month are allowed to be produced by each swordsmith, and all swords must be registered with the Japanese Government.
  Outside Japan, some of the modern katanas being produced by western swordsmiths use modern steel alloys, such as L6 and A2. These modern swords replicate the size and shape of the Japanese katana and are used by martial artists for iaidō and even for cutting practice (tameshigiri).
  Mass-produced swords including iaitō and shinken in the shape of katana are available from many countries, though China dominates the market. These types of swords are typically mass-produced and made with a wide variety of steels and methods.
