Nakamura Gatana (translated into "dull-edged-sword"), is a short comedy about a samurai and his worn down sword which turns completely useless as he tries to fight even the weakest opponents. The samurai, trying to figure out why his old sword won't cut anyone he strikes, tries desperately to attack random townspeople who of course defend themselves and knock him out.
