Tameshigire is the Japanese, sport or art of cutting tatami mats with a sword. Traditionally, a rolled up tatami mat soaked in water overnight is considered to be as hard to cut through as a human thigh. The current record is 25 mats cut through with a Daito sword made by Angel Sword of Dripping Springs Texas. https://www.bing.com/videos/search?q...F2131A6ABED510
