The Soto Maru Nomi is a Japanese curved chisel (incannel gouge) with a convex, outward-curving cutting edge, designed for accurate shaping of curved and round work. The blade is traditionally laminated, with a hard high-carbon steel cutting layer forge-welded to a softer steel body to provide edge retention, support, and shock absorption.
This tool excels at cutting and refining curved surfaces, undercuts, and work executed at or near 90 degrees to the surface, and is commonly used in sukiya and teahouse construction traditions. It is particularly effective for dialing the final fit of scribe-fit joints, allowing precise adjustment where timber or frame members meet stone or other irregular surfaces.
The convex back of the Soto Maru Nomi makes it straightforward to sharpen, as the single-plane bevel can be honed directly on a flat sharpening stone, allowing for controlled edge maintenance and consistent cutting performance.
