The Samurai of feudal Japan revered the sword, known as the Katana, to an almost religious state. Swords were highly prized and took a long time to forge. The Samurai used to test a new sword to determine its cutting and handling abilities. It was known as “Tameshigiri” (“Test Cutting”). In more brutal days it was done on condemned prisoners or corpses. It evolved into rolled mats of bamboo soaked in water until they had the approximate density of human flesh. As you can see here these swords are SHARP!
