SunTiger Rough Grain Sharpening Stone - #220

To obtain a truly sharp edge, you must hand sharpen your Japanese knives with Japanese water stones. The process of sharpening on a stone is not unlike sanding wood; the whetstone scratches away material from the blade in stages to shape and polish the metal to an acute edge. Water stones come in a broad range of grits, from very rough to fine, for this purpose. They are referred to as water stones as water is the lubricant adding the sharpening process. Rough (#80-220) stones are intended for experienced sharpeners; their abrasiveness makes them ideal for repairing damaged knives but can easily ruin a knife edge if used improperly. Our standard synthetic sharpening stones, made from materials such as Aluminum and Silicon Carbide, are versatile and easy to use. They are suitable for a wide variety of knife steels. With use, a synthetic stone will become slightly concave in the middle and, as a flat surface is necessary for sharpening, they need to be leveled out routinely with a stone fixer. Synthetic stones must be soaked in water for 10 minutes before use.
