The notion that the historical figure Hattori Hanzo stopped making swords is a misconception rooted in fictional portrayals rather than historical facts. Hattori Hanzo, also known as Hattori Masanari, was a samurai and a prominent retainer of the Tokugawa clan during the Sengoku period in Japan.

Hattori Hanzo was renowned for his exceptional skills as a warrior and strategist, serving as a key figure in various battles and campaigns. While he was not primarily known as a swordsmith, he did have expertise in weaponry and was skilled in using various weapons, including the sword.

The idea that Hattori Hanzo stopped making swords likely stems from his portrayal in popular culture, notably in movies and other fictional works. In some of these fictional depictions, Hattori Hanzo is often shown as a retired or reclusive swordsmith, who, for various reasons, has chosen to no longer create weapons. These portrayals add an element of intrigue and mystique to the character, contributing to the mythos surrounding Hattori Hanzo.

It's important to recognize that the historical Hattori Hanzo's primary role was as a warrior and retainer rather than a renowned swordsmith. While he may have had knowledge of weapons craftsmanship, there is no historical evidence to suggest that he completely ceased making swords during his lifetime.
