Frequently Asked Questions What is the difference between the 400 and 1000 grit surfaces? The medium 400 grit surface removes material more quickly and is suitable for restoring dull edges. The fine 1000 grit surface smooths out marks from previous sharpening and gives the blade a more refined edge. Do I always have to use both sides? No. If the knife only needs a light touch-up, the 1000 grit surface may be sufficient. For a clearly dull blade, start with the 400 grit side and finish with the finer 1000 grit surface. Does the diamond stone need to be soaked in water before use? No. This is not a traditional water-absorbing sharpening stone, but a diamond-coated plate fixed to a metal base. The diamond surface can be used dry and does not need to be soaked before sharpening. Can I use a honing solution during sharpening? Yes. Although the diamond surface can be used dry, Smith’s Honing Solution can help remove metal particles from the surface and make sharpening smoother. Use only the solution recommended by the manufacturer and follow its instructions. What is the protective cover for? The cover protects the diamond surfaces during transport and storage. During sharpening, the cover can be placed under the plastic base to raise the working surface higher and give your hands more safe movement space. Is the sharpening stone suitable for serrated knives? The flat diamond surface is primarily intended for straight edges. To sharpen the individual serrations of a serrated knife, use a conical diamond rod of the appropriate diameter. When is Smith’s 400/1000 Diamond Stone the right choice? The double-sided diamond stone is suitable for users who want more control over the sharpening angle, pressure, and blade area compared to a pull-through sharpener. The combination of 400 and 1000 grits covers standard basic sharpening and subsequent finishing without needing to buy several separate stones. For restoring very deep nicks or heavily damaged edges, a coarser abrasive than 400 may be needed. For a mirror-polished finish, it’s worth following the 1000 grit with an even finer stone or a leather strop. For quick sharpening outdoors, a compact pull-through sharpener is more convenient, while a conical diamond rod is better for serrated blades. Expert tip Place the protective cover under the base during sharpening to raise the diamond surface above the work area. Set the system on a stable, non-slip surface. Keep the blade at as consistent an angle as possible throughout the movement and use light pressure—the diamond coating removes metal efficiently and does not require strong force. For moderately dull knives, start with the 400 grit surface and work both sides of the blade evenly. Once the edge is evenly restored, continue on the 1000 grit, gradually reducing pressure. For slightly dull blades, start directly with the finer side. The diamond surface can be used dry, but an appropriate honing solution helps remove metal particles from the surface. After use, clean the plate according to the manufacturer’s instructions, dry it, and apply the protective cover. Do not press hard with the blade, as excessive pressure may accelerate uneven wear of the diamond coating. Double-sided diamond stone for controlled sharpening Smith’s 400/1000 Diamond Stone combines a medium and a fine diamond surface on a compact 15 cm base. It is a practical choice for regular maintenance of straight-edged knives when you want fast material removal, a controlled sharpening angle, and a smoother finish.
