The EdgeCrafter 400DS Diamond Sharpening Stones are top-notch! The Chef's Choice EdgeCrafter 400DS has ultra-flat and highly durable diamond stones. Plated with 100% diamond abrasives at the perfect grit for single-stone sharpening, they can sharpen various materials like tungsten carbide, tool steel, ceramic, and more. These stones can give a great edge to sports and kitchen knives, axes, arrowheads, etc. EdgeCraft's unique nickel plating process firmly bonds diamonds to a steel support plate in a precision-built hardwood box. The steel plate stays flat without dishing. Optimal diamond spacing stops the abrasive surface from getting clogged. An engraved hardwood cover protects the stone when not in use. No need for messy sharpening oils. Rubber feet keep the stone stable on the work surface. Available in 2x4, 2x6, and 2x8 inches.

Using the Chef's Choice 400DS EdgeCrafter 2x4 Diamond Sharpening Stone is easy. First, place the stone on a flat surface like a bench or table. The rubber feet will keep it steady. Then, take the item you want to sharpen, like a knife or an axe, and gently move it across the stone at an appropriate angle. You can repeat this several times until you get the sharp edge you desire. Remember, the stone is very durable and has 100% diamond abrasives, so it can handle various materials. When you're done using it, put the engraved hardwood cover back on to protect the stone. There's no need to use any messy sharpening oils or lubricating liquids. As for maintenance, just keep it clean and dry. Avoid dropping it or hitting it hard, as this could damage the flat steel surface with the bonded diamonds. If you notice any debris on the stone, you can gently brush it off. This way, your sharpening stone will last you a long time and keep working great.
