No, Sasuke Uchiha does not have a katana as a part of his regular arsenal. While he is a skilled and versatile shinobi, Sasuke's primary weapons are his ninjutsu and his unique abilities granted by his Sharingan and Rinnegan.

Although Sasuke has been depicted using a sword on occasion, it is not a consistent or prominent aspect of his fighting style. The sword he occasionally wields is called "Chidori Blade" or "Sword of Kusanagi," which is a lightning-infused blade created using his Chidori technique or his manipulation of the Kusanagi sword's chakra. However, this sword is not a traditional katana but a manifestation of his chakra and abilities.

In general, Sasuke relies more on his exceptional speed, agility, and his various jutsu to engage in combat rather than primarily using a physical sword.
