Fallkniven DC521 Bench Stone – Diamond & Ceramic, 210 mm

The Fallkniven DC521 Bench Stone is a professional-grade dual-surface sharpening stone designed for tools, chef knives, outdoor gear, and high-performance steel blades. Combining diamond grit (25 micron) for aggressive sharpening and ceramic grit (5 micron) for ultra-fine honing, this precision-flat stone guarantees razor-sharp results. Delivered in an elegant gift box, the DC521 is both a practical sharpening solution and a premium tool for enthusiasts and professionals.

The DC521 was created to provide an all-in-one sharpening solution that balances speed with precision. Its design ensures even thick or very dull edges can be restored quickly on the diamond surface, while the ceramic side delivers the smooth, razor finish required for precision cutting.

Ideal for professional chefs, hunters, outdoor enthusiasts, craftsmen, and knife collectors who demand consistent results. This stone is also an excellent choice for anyone using modern high-hardness steels that are difficult to sharpen with traditional whetstones.

To use the DC521, start with the diamond side to restore dull or thick edges. Once the edge has been shaped, switch to the ceramic side to refine and polish it to razor sharpness. No oil or water is needed for sharpening, but it is recommended to keep the surfaces clean with warm water and mild soap.

The DC521 reflects Fallkniven’s philosophy of combining modern materials (diamond and synthetic sapphire ceramic) with Scandinavian craftsmanship to create tools that endure in demanding environments.

Micron: A micrometer (µm) is one-millionth of a meter. The grit size of sharpening stones is often described in microns, where smaller numbers mean coarser grit and larger numbers finer grit.
Diamond Grit: Industrial diamond particles used as an abrasive for rapid, precise metal removal.
Ceramic Stone: A fine abrasive surface made of synthetic sapphire, ideal for polishing and final honing.
