Yes, fighting with two katanas, a style known as "nito" or "nitōryū," is a technique that has been historically practiced by some samurai warriors in feudal Japan. It involves wielding a katana in one hand and a shorter sword, often a wakizashi, in the other.

The use of two swords allowed the samurai to engage in dual-wielding combat, utilizing different techniques and strategies. It provided versatility, speed, and the ability to attack from multiple angles simultaneously. The longer katana could be used for powerful cuts and strikes, while the shorter sword offered increased agility and precision.

Dual-wielding required considerable skill, coordination, and ambidexterity to effectively manage both swords simultaneously. The samurai would need to be able to flow seamlessly between different techniques and adapt to the changing dynamics of the fight.

It is worth noting that dual-wielding two katanas was not a common or mainstream practice among samurai. It was primarily associated with specific schools or individuals who specialized in this style. Examples include the Niten Ichi-ryū style founded by the legendary swordsman Miyamoto Musashi, who famously fought with two swords.

If you are interested in learning the art of dual-wielding with two katanas, it is important to receive proper training from qualified instructors who can teach you the specific techniques, principles, and safety considerations associated with this style. It requires dedicated practice and a deep understanding of the underlying principles of swordsmanship.

As always, safety and responsible use of any weapon should be prioritized, and adherence to local laws and regulations is crucial.
