The top-quality Spyderco ceramic sharpening steel fine, 204F1 is perfect for use in the Spyderco Sharpmaker.
You can, however, also use this sharpening steel without the Sharpmaker. The triangular shape with special sharpening groove is perfect for various sharpening jobs. The material the sharpening steel is made from consists of industrial synthetic sapphire. With it you can also easily sharpen harder metals!
Here it concerns a fine sharpening steel that can be used to keep your knives in great condition or to make them even sharper. Sharpening a blunt knife, however, is better on a coarser sharpening steel such as the Spyderco coarse diamond-coated sharpening rods. You can, however, sharpen them even finer on the Spyderco ceramic sharpening steel ultra-fine, 204UF1.
Please note: here it concerns one sharpening steel!
