Yes, samurai often used two swords simultaneously as part of their armament. This practice, known as "daisho," refers to the wearing of a pair of swords consisting of a longer sword (katana) and a shorter sword (wakizashi) together. The daisho was a symbol of the samurai's social status and adherence to the samurai code of bushido.

The longer sword, the katana, was the primary weapon of the samurai. It typically had a curved, single-edged blade and was wielded with two hands. The katana was versatile and well-suited for slashing and cutting techniques in various combat situations.

The shorter sword, the wakizashi, had a similar design to the katana but with a shorter blade length. It was worn alongside the katana and served as a backup weapon. The wakizashi was used for close-quarters combat, indoor fighting, or situations where drawing and maneuvering the longer katana would be impractical.

The daisho was more than just a practical choice; it held cultural and symbolic significance as well. The pair of swords represented the samurai's readiness for different combat scenarios and served as a visible symbol of their social status. It showcased the samurai's commitment to honor, loyalty, and martial skill.

It's worth noting that the use of the daisho varied over time and among samurai of different ranks. During the Edo period (1603-1868), regulations were put in place to control the size and type of swords that samurai could carry, leading to variations in the lengths and styles of the daisho.
