The swords in anime are typically referred to by their specific names or classifications, just as they would be in the real world. Here are some common sword terms used in anime:

1. Katana: The katana is a traditional Japanese sword with a curved, single-edged blade and a circular or squared guard. It is one of the most iconic and widely recognized swords in anime and Japanese culture.
2. Nodachi/Odachi: These terms are used to describe exceptionally long Japanese swords with blades over 90 centimeters (35 inches) in length. Nodachi and odachi are often depicted in anime as powerful and imposing weapons.
3. Tachi: The tachi is a type of Japanese sword that predates the katana. It has a slightly curved blade and is traditionally worn suspended from the belt, with the cutting edge facing down.
4. Wakizashi: The wakizashi is a shorter sword, usually measuring between 30-60 centimeters (12-24 inches) in length. It is often paired with the katana and worn together by samurai.
5. Jian: The jian is a double-edged straight sword from China. It has a slender, balanced blade and is associated with Chinese martial arts and historical dramas in anime.
6. Zanpakuto: In the anime series Bleach, Zanpakuto refers to the spiritual swords wielded by the Shinigami characters. Each Zanpakuto has its own name, abilities, and unique appearance.
7. Broadsword: The term "broadsword" is used to describe large, two-handed swords with straight or slightly curved blades. They are often depicted in fantasy-themed anime, particularly in settings inspired by medieval Europe.

These are just a few examples, and the swords in anime can encompass a wide range of designs and names based on the specific series, setting, and cultural influences. The variety of swords in anime reflects the diverse range of cultures, mythologies, and storytelling traditions that inspire the medium.
