Eiji-hi Seal Carving Knife (Engraving Knife for Seal Carving)

Seal Knives Crafted with Alloy and Superalloy Blades

Eiji-brand seal knives feature a core blade made from high-quality alloy or superalloy, designed to deliver exceptional durability and long-lasting sharpness.
These advanced materials help reduce chipping and maintain cutting performance far longer than standard blades.

When examined under a tool microscope, the blade edge appears remarkably straight, providing smooth, controlled sharpness that supports precise seal carving.
Because the blade core contains alloy or superalloy materials, we recommend using an oil stone or diamond whetstone when re-sharpening to maintain optimal performance.
