Seal Knives — The Essential Tool of Seal Carving
Just as brushes are indispensable in calligraphy, seal knives are the core tools of seal carving.
A well-balanced and sharp seal knife has a direct impact on carving precision,
line quality, and the final finish of the seal.
At Shoyu Online, we select seal knives that emphasize stability, sharpness, and reliability,
allowing both beginners and professionals to carve with confidence.
Types of Seal Knives
Seal knives are generally classified into double-edged knives, known as “Chūhō,”
and single-edged knives, known as “Katahō.”
Chūhō knives are widely used for stone seals:
thicker blades are suitable for softer stone, while thinner blades perform well on harder materials.
Katahō knives are commonly chosen for carving wood or bamboo seals.
For beginners, a medium-width blade offers good control and versatility, making it an excellent starting choice.
