The katana is characterized by its long, slender blade, which is typically around 2.5 to 3 feet in length and has a distinctive curve that allows it to be wielded with great speed and precision. The handle, or hilt, of the katana is typically made of wood and is wrapped in a special type of cord called "tsuka-ito" to provide a secure grip. The katana is worn with the edge facing upward, with the handle facing down, and is traditionally worn with the hilt protruding from a sash called an "obi."
In addition to its use as a weapon, the katana is also revered for its beauty and craftsmanship, with many katanas being considered works of art in their own right. The process of forging a katana involves a number of complex steps and requires a high level of skill and attention to detail. As a result, katanas are often considered to be symbols of honor and prestige, and are highly prized by collectors and enthusiasts.
