Silicon carbide stones are popularly used to sharpen hard stainless steel knives quickly and aggressively due to their faster sharpening time and more durable grit that doesn’t dish easily. High carbon steels will generally not pose any problems for most stone types, including natural Arkansas stones and aluminum oxide stones; however, some steels require more specific solutions. Grit A sharpening stone’s grit rating measures its coarseness or fineness and effectiveness at creating a cutting edge. A lower grit stone will suffice for roughing out initial cuts while higher-grit stones provide greater opportunities for refining and polishing cutting edges. Green silicon carbide (GSC) is the go-to material for grinding stones. Produced …
