A Hanzo sword, specifically referring to a sword crafted by a historical figure named Hattori Hanzo, does not exist. Hattori Hanzo was a real historical figure in Japan during the Sengoku period (15th-17th century), known for his skills as a ninja and samurai. However, there is no evidence or historical record of him being a swordsmith or creating swords.

The concept of a "Hanzo sword" gained popularity and recognition primarily through its fictional portrayal in Quentin Tarantino's movie Kill Bill. In the film, Hattori Hanzo is depicted as a legendary swordsmith who creates extraordinary swords, including the one used by the protagonist. However, it's important to note that this portrayal is entirely fictional and not based on historical fact.

If you come across swords referred to as "Hanzo swords" outside of the context of the movie, it's likely that they are replicas or inspired designs created by modern swordsmiths or enthusiasts. These swords are not associated with the historical figure Hattori Hanzo and do not possess any historical or cultural significance beyond their individual craftsmanship.
