Yes, samurai warriors often carried a tanto as a secondary weapon alongside their primary swords, such as the katana and wakizashi. The tanto is a short dagger or knife with a single or double-edged blade, typically measuring around 15-30 centimeters (6-12 inches) in length.

The tanto served various purposes for the samurai. It was primarily used as a close-quarters weapon for stabbing and slashing in tight spaces or when a shorter blade was advantageous. The tanto could be used as a backup weapon if the samurai's main sword was lost, damaged, or unsheathed. It was also employed for utility tasks, such as cutting objects, opening packages, or performing everyday tasks.

In addition to its practical uses, the tanto held symbolic significance for samurai. It was considered a symbol of the samurai's honor and served as a personal statement of their resolve and dedication to their code of conduct. Some samurai would have their tanto crafted with intricate and decorative designs, showcasing their status and personal style.

The tanto was often carried in a separate scabbard or tucked into the belt, allowing for easy access when needed. The samurai would draw the tanto with a reverse grip, known as "gyaku-hanmi," using a different set of techniques compared to the primary swords.

While the tanto was an essential part of a samurai's armament, its exact usage and prominence varied depending on the specific period, school of martial arts, and individual preferences of the samurai.

Overall, the tanto served as a versatile and practical secondary weapon for the samurai, providing them with a close-quarters combat option and a tool for various tasks.
