Premium Tenba Seal Carving Knife (High-End Tenkoku Knife)

A Genuine Masterpiece Forged by a Master Swordsmith

This exceptional seal knife is forged by a master swordsmith using traditional steel-forging techniques, the same methods employed in the creation of Japanese swords.

Developed as a collaborative project with Shoyu under the guidance of renowned seal engraver Seia Manabe, this knife represents the highest level of craftsmanship and precision.

For serious seal engraving (tenkoku), especially when carving seal stones, we strongly recommend using an authentic seal knife forged by a swordsmith, designed to deliver outstanding sharpness, control, and durability.
