Tachi

The tachi has a distinctive style and construction, with a longer handle and a more pronounced curve compared to the katana. The blade is typically made from high-quality steel, with a sharp cutting edge and a strong spine. The tachi was often adorned with elaborate fittings and decorations, reflecting the status and wealth of the samurai who owned it.

In battle, the tachi was a versatile weapon, capable of delivering powerful cuts and thrusts. Its longer length and curved shape allowed for greater reach and cutting power, making it effective against both armored and unarmored opponents. The tachi was also used for ceremonial purposes, such as during weddings and formal events.

Over time, the tachi fell out of favor and was eventually replaced by the katana as the preferred sword of the samurai. However, the tachi remains an important part of Japanese sword history and is highly valued by collectors and enthusiasts for its unique design and historical significance.
