What is a seppa on a katana

katana seppa

Derived from the Japanese term '切羽', which translates as 'cutting wing', the seppa is a metal spacer or washer that resides on both sides of the sword’s tsuba (handguard). Its primary role is to ensure a tight and secure fit of all components of the sword's hilt.

The Functions of the Seppa

Essentially, this metal disc serves a dual role: ensuring security and maintaining balance. By filling any additional space on the sword's tang, it ensures that all components of the hilt, such as the tsuba, fuchi (sleeve), and tsuka (handle), are securely fastened, preventing any unnecessary movements or rattling during handling.

Moreover, it contributes to the overall balance of the sword, which significantly impacts the weapon's handling and performance during use.

Materials Used in Crafting Seppa

While the seppa may appear simple, the choice of material and craftsmanship involved in creating this small but vital component is anything but. Seppa are typically crafted from various metals such as copper, brass, or silver, often chosen for their strength, durability, and aesthetic appeal.

Copper Seppa

Copper is a popular choice due to its malleability and corrosion resistance. Its warm, reddish-glow adds a subtle contrast to the otherwise dominant steel grey and black hues of the sword, enhancing the sword’s overall aesthetic appeal.

Brass Seppa

On the other hand, brass seppa are renowned for their durability and resistance to wear. They showcase a golden-yellow shine, adding an elegant touch to the weapon.

Silver Seppa

Lastly, silver seppa often adorn high-end katanas due to their luxurious appeal and excellent resistance to corrosion. While silver seppa demand higher maintenance to prevent tarnishing, their sophisticated aesthetic more than compensates for the extra care required.
