Tameshigiri

Tameshigiri (試し斬り, 試し切り, 試斬, 試切) is the Japanese art of target test cutting. The kanji literally mean "test cut" (kun'yomi: ためし ぎり tameshi giri). This practice was popularized in the Edo period (17th century) for testing the quality of Japanese swords and continues through the present day.
