OVERVIEW & PRODUCT DESCRIPTION
Achieve maximum-width masonry trimming, rigorous concrete demolition, and professional stone surface reduction with unmatched durability and traditional Japanese precision using the Naniwa Carbide Hatsuri Nomi Stone Chisel (Model #1139).

Manufactured by Naniwa—renowned for exceptional carbide tooling and industrial abrasives—this professional-grade stone chisel features a massive, solid 30mm round body (直径30パイ) paired with a heavy-duty, wide tungsten carbide tip (10x10x30mm dimensions) securely embedded at the cutting edge. The robust carbide tip provides exceptional wear resistance, impact toughness, and long-lasting hardness, allowing the tool to slice through hard stone, granite, concrete, and masonry across a broad surface without frequent re-sharpening. Weighing a solid, balanced frame with an overall length of 190mm, it delivers maximum impact transmission and structural rigidity required for heavy-duty striking work.

Whether used for professional stone masonry, architectural restoration, wide concrete surface prep, or artistic stone carving, this authentic Japanese tool delivers uncompromising performance and enduring reliability.
