Overview
This white alumina oil sharpening stone is engineered for professional workshops and industrial maintenance applications requiring aggressive material removal. It serves as an essential first step in tool and blade reconditioning, efficiently reshaping damaged or dull edges. The coarse 150-grit abrasive is formulated for rapid stock removal, preparing surfaces for subsequent finer honing stages. Its standardized dimensions ensure compatibility with a wide range of manual sharpening guides and powered fixture systems.
