Rainline Katana

Materials & Craftsmanship
We choose the right steel for each katana—nothing more, nothing less |
|
One continuous piece of steel, from blade to handle |
|
Through-hardened or clay-tempered, years of experience get it just right |

Hand-Fitted Koshirae
Shaped to follow the katana’s curve, with a secure fit for a smooth draw without slipping loose |
|
For centuries, the tsuba has reflected its owner’s taste—and is often the first detail to catch the eye |
|
A comfortable shape, a tight wrap—the first step to bringing out a katana’s true power is a firm grip |
