Hattori Hanzo is portrayed as a master swordsmith and former assassin who creates exquisite and deadly swords.

The Hattori Hanzo sword depicted in Kill Bill is a highly revered weapon known for its exceptional craftsmanship and sharpness. It is a katana, a traditional Japanese sword with a curved, single-edged blade. The sword shown in the movie has a long blade, typically around 60 to 80 centimeters (24 to 31 inches), and is designed to be wielded with two hands.

It's important to note that the Hattori Hanzo sword, as portrayed in Kill Bill and other fictional works, is entirely fictional and does not have any historical basis. The character of Hattori Hanzo and his swords were created for the purpose of storytelling and cinematic entertainment.
