Description Made in Solingen The Material All sharpening steels are made of alloyed tool – steel of 1.15 % carbon, 0.6 % chromium, and 0.03 % vanadium. Due to this alloy, the sharpening steel is highly wear-resistant, which is important since the hardness of steel used for knife blades is constantly increasing. The Surface of Sharpening Steels Sharpening Steels have three different surfaces: Medium fine grain: Typical for kitchen steels, this steel quickly forms a new burr at the edge of a blade for a smooth cut. Fine grain: Recommended for butchers who sharpen their blades on a grinding machine, and use a sharpening steel in addition to raise a burr for a smooth cut. Polished surface: For use in slaughterhouses, performs the same as the fine grain.
