Restoration Services — 修復作業
Restoring Respect to the Blade
Not every sword needs a full polish.
Some need cleaning, some need correction, and some need their dignity returned after years of neglect.
Restoration is where Isshin Katana brings a blade back into harmony — without overworking the steel or erasing its story.
