Katana vs Uchigatana: What Is the Difference?

The katana and the uchigatana are two of the most popular and best-known traditional Japanese swords. Both emerged during the feudal period and were carried and used by the samurai. The katana and the uchigatana share a similar design, including a curved blade, but there are notable differences between the two that should not go unnoticed. What exactly is the difference between the katana and the uchigatana, and which of these traditional Japanese swords is better?

Overview of the katana

The katana appeared in Japan during the Kamakura period (1185 to 1333). At the time, the term "katana" described a single-edged, curved sword longer than the tachi. It was produced out of a need for better blades. During the Kamakura period, Japanese armies struggled to defend their lands against the Mongols because of the thick, hard leather armour worn by their opponents.

The samurai found that their swords could not pierce Mongol armour. Swordsmiths therefore began work on new swords, which led to the invention of the katana.

As you may know, the katana is characterised by a single-edged curved blade, which has made it famous around the world. By designing the katana this way, the swordsmiths of feudal Japan were able to create a better sword, one able to cut easily through hardened leather armour. The curve of the blade, together with the use of high-carbon steel, allows it to flex without breaking.

Overview of the uchigatana

A descendant of the tachi, the uchigatana is a traditional Japanese sword that, like the katana, dates back to the Kamakura period. If you compare a photo of a katana with one of an uchigatana, you probably will not be able to tell them apart.

That is because both traditional Japanese swords have a single-edged curved blade and both measure between 58 and 71 cm (22.8 to 28.0 in) in length.

The difference between the katana and the uchigatana

The main difference between the katana and the uchigatana lies in their quality of manufacture. The katana is generally considered the higher-quality sword, made with first-rate materials and superior craftsmanship. A bladesmith would typically take months to produce a katana, whereas an uchigatana could be built in just a few weeks.

According to Wikipedia, the uchigatana was an expendable sword because of its lower-quality construction. After using one, a samurai would discard it and replace it with a new one. For this reason, few or no examples of genuine traditional Japanese uchigatana survive today.
