    Image of Product. Front orientation. Sharpening Stones. Straight, Rectangular Stone, Two Grit.

    Two Grit

    Two Grit—A different grit on each side enables two-step sharpening with one stone. First sharpen your blade with a lower grit, then sharpen again with a finer (higher) grit until the desired edge is achieved.
    Aluminum Oxide Abrasive—Aluminum oxide cuts more slowly than silicon carbide for finer control. Also known as India stones.
    Silicon Carbide Abrasive—Silicon carbide cuts quickly with light pressure. Also known as Crystolon stones.
    Ceramic Alumina Abrasive—Ceramic alumina is extremely hard and wear resistant.
    Novaculite Abrasive—Novaculite has extremely fine grains that cut very slowly for the most control over sharpening. Also known as Arkansas stones.
    Leather Pouch and Plastic Pouch—Store your stone in a pouch and slip it into your pocket when you're on the go.

    Diamond Sharpening Stones

    Sharpen blades of any material with the hardest and longest-lasting abrasive we offer. The diamond surface keeps its shape and finish without lubricants, so you can use these stones dry or with water. Rinse with water to clean.

    Shallow dimples collect debris to prevent clogging the sharpening surface. These stones are a good choice for blade edges with defects that require heavy material removal. They also reduce friction and heat to protect delicate blades while you sharpen.
    Antislip Feet and Antislip Mat—Keep the stone in place to maintain a steady angle while you sharpen.

    The dimple-free surface sharpens blades evenly every time. Since these stones have the most abrasive, they also remove material more quickly. However, debris can build up rapidly, so you’ll need to wipe them clean more often.

    Water-Activated Sharpening Stones

    Sharpen cutting edges faster and with less pressure than standard stones. Instead of applying a lubricant, add a few splashes of water to form an abrasive slurry. The slurry removes imperfections efficiently, exposing fresh grit as it forms.
    For duller blades, sharpen with multiple stones, moving from coarser to finer grits. Use 220 grit to smooth away damage, 500 grit for the initial pass, 1200 grit for polishing, and 1400 grit for an ultra-fine, mirror-like finish.
    Add a mat to catch the slurry and keep your work area clean.
