    Sharpening Stones

    Sharpen tools on your bench top. Use these sharpening stones with a water-soluble or oil-based lubricant.
    Straight Rectangular Stone—For Straight Blade Edges
    Image of Product. Front orientation. Sharpening Stones. Straight Rectangular Stone—For Straight Blade Edges, 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—Extremely hard and wear resistant, these stones sharpen your hardest blades. They cut hard materials slower than cubic boron nitride (CBN) and diamond for finer control.
    Novaculite Abrasive—Novaculite has extremely fine grains that cut very slowly for the most control over sharpening. Also known as Arkansas stones.
    Oil Filled—No need to stop and clean these stones as you polish—they’re filled with oil to keep debris from getting stuck in their pores. You’ll also need an oil-based lubricant to wash away debris and reduce friction and heat on your workpiece.
    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.

    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.
