A while ago I wrote about Seppuku, Katanas, and Samurai and made a joking reference to Hattori Hanzo.
In my comments someone named Lazken notes that a Hattori Hanzo did exist, but he did not make swords. You can read about Hanzo in the samurai archives.
Lazken goes on to say that we watch too many Kill Bill movies. Umm... dude... there's only two of them. ;)
