A set consisting of a katana and a wakizashi is referred to as a "daisho" in Japanese. The term "daisho" translates to "big-small" or "long-short" and specifically indicates the pairing of two swords of different lengths.

The daisho traditionally consists of a katana, which is the longer sword with a curved blade, and a wakizashi, which is the shorter sword with a similar design. The katana typically has a blade length of around 60-70 centimeters (24-28 inches), while the wakizashi has a blade length of approximately 30-60 centimeters (12-24 inches).

Historically, the daisho was worn by samurai as a symbol of their social status and privilege. It denoted their rank and was an indication of their readiness for different combat situations. The katana was the primary battlefield weapon, while the wakizashi served as a backup weapon for close-quarters combat, indoor use, or as a symbol of their authority.

The daisho set had practical and cultural significance in feudal Japan, representing the status and honor of the samurai. The pairing of the katana and wakizashi signified the samurai's preparedness for a range of combat scenarios and their adherence to the warrior code of bushido.

In contemporary times, the daisho is still revered as a symbol of the samurai tradition and is often displayed as a collector's item or used ceremonially. While the practical use of the daisho in combat has diminished, the historical significance and aesthetic appeal of owning a katana and wakizashi set continue to captivate enthusiasts and collectors.
