A katana tsuba refers to the handguard specifically designed for a katana, which is a traditional Japanese sword with a curved blade. The tsuba serves as a protective guard between the blade and the wielder's hand, preventing the hand from sliding onto the sharp edge during combat and providing stability during sword handling.

The katana tsuba is typically round or slightly oval in shape, with a central opening (nakago-ana) through which the tang (nakago) of the sword passes. The size and design of the tsuba can vary significantly, depending on factors such as historical period, regional style, and personal preference.

Katana tsuba designs can be quite intricate and elaborate, often featuring motifs from nature, mythology, samurai culture, or historical events. Some tsuba may also include inscriptions, family crests (mon), or artist signatures. They are often made from various materials, including iron, brass, copper, or alloys, and can be decorated using techniques such as carving, engraving, inlay work, or patination.

Beyond its protective function, the katana tsuba also contributes to the overall balance of the sword, allowing for better handling and maneuverability. It is an essential part of the katana's aesthetic appeal and is considered an art form in itself, with collectors and enthusiasts appreciating the craftsmanship and artistic value of finely crafted tsuba.

It's important to note that the design and style of katana tsuba have evolved over time, and there can be regional and historical variations.
