What is japanese shortsword?

The Japanese shortsword, commonly known as the wakizashi, is a traditional Japanese weapon that is often paired with the longer katana. It typically measures between 30-60cm in length and has a single-edged, curved blade. Historically, the wakizashi was used by samurai for close combat and indoor fighting, as well as for self-defense and ritual suicide. It was also used as a backup weapon in case the katana was damaged or lost. The wakizashi was made using a similar process as the katana, with a high-quality carbon steel blade, and was often decorated with intricate designs and symbols. Today, the wakizashi is still used in traditional Japanese martial arts like kendo and iaido, as well as in modern-day cosplay and martial arts demonstrations.
