What is Katanagari in Japanese Katana terminology?

"Katanagari" (刀狩り) refers to the law enacted by Toyotomi Hideyoshi in 1588 (Tensho 16) that prohibited anyone other than samurai from possessing swords. By banning farmers from carrying swords, Hideyoshi advanced the separation of warriors and farmers, known as "Heinou Bunri".

However, the practice of ""Katanagari"", which involves forcing non-samurai to relinquish their swords, has been carried out since the Kamakura period. The first instance of this was in 1228 (Antei 2), when Hojo Yasutoki, the regent of the Kamakura shogunate, enforced it against the monks of Koyasan."
