Hanzo is the well-endowed samurai from the cult trilogy Hanzo the Razor. Hanzo is best described as a Japanese amalgamation of Shaft and Dirty Harry. He practiced sadomasochism to further hone his strength and sexual prowess. Examples include pounding his penis into a block of wood with a mallet and humping a dry bag of rice.
