Nihonto refers to traditional Japanese swords, often specifically referring to those made prior to the Meiji era (1868-1912). The term "Nihonto" translates to "Japanese sword" in Japanese.

Nihonto are highly esteemed for their craftsmanship, artistry, and historical significance. They are renowned for their meticulous forging techniques, the use of high-quality steel, and the artistry displayed in their design and ornamentation. Nihonto blades are typically made through a process of careful forging, folding, and shaping, followed by the application of a differential hardening technique known as "yaki-ire."

Nihonto can be classified into several types based on their length and design, such as katana (long swords), wakizashi (medium-sized swords), and tanto (short swords). Each type serves different purposes and holds its own cultural and historical significance.

Collecting, preserving, and appreciating Nihonto is a specialized field known as Nihontō study. Due to their historical value and cultural importance, authentic Nihonto are highly regulated in Japan, and their sale and export are subject to specific laws and regulations.

It's important to note that Nihonto are distinct from mass-produced replicas or decorative swords. Authentic Nihonto hold great value to collectors, historians, and enthusiasts who appreciate their craftsmanship, historical context, and cultural significance.
