Sword Restoration — Can a Broken Blade Be Repaired?

Japanese swords are delicate art objects made of steel. Over centuries, they may sustain various forms of damage.

Chip repair: Small edge chips can be removed through polishing, but large ones may alter the blade's profile. Consult with a togishi before deciding.

Rust removal: Surface rust can be polished away. However, deep pitting rust (mushikui-sabi) cannot be fully removed and affects aesthetic value.

Broken blades: Welding a broken sword is technically possible, but drastically reduces its art value. Preserving the break may better maintain historical significance.

When NOT to restore: Historical battle damage tells the sword's story and serves as important provenance evidence. Hasty restoration can diminish rather than enhance value.

Restoration decisions are best left to experts. We offer consultation on restoration matters.
