Blade Sharpeners

Pass your knife or scissor blades over the abrasive stones to restore dull edges.

For Sharpening Knives

Shown in Use with Knife

Carbide Abrasive—For coarse sharpening, carbide aggressively removes material to form a new edge.

Ceramic Abrasive—For use after coarse sharpening, ceramic refines and polishes your blade’s edge. You can also use ceramic to touch up blades that are still somewhat sharp.

Reversible Sharpening Stones—Double the life of your sharpener. These abrasive stones have two sharpening surfaces, so you can flip them when one face becomes dull to reveal a fresh one.

Adjustment Dial—Turn the dial to switch between six different sharpening angles.

Electric Blade Sharpeners

Make your blade as sharp as the day you bought it with minimal effort. These sharpeners have preset angle guides to make sure your blade strikes the abrasive at the correct angle—every time.

For Sharpening Knives


	Removable Sharpening Unit

Draw your knife through each of the three slots—there’s no need to swap out belts to change abrasive levels. Two slots have diamond abrasive wheels for sharpening: one with a coarse abrasive and one with a medium abrasive. The final slot has a leather wheel for polishing your blade to a razor-sharp finish.

Diamond Abrasive—Our hardest abrasive. Diamond can sharpen any blade material, even hardened steel.

Leather Abrasive—For a polished finish after you’ve already sharpened with coarser abrasives, leather removes microscopic burs from blade edges. Also known as strops.

Removable Sharpening Unit—Detach the sharpening unit to manually clean and sanitize the slots. You can also place it in a commercial dishwasher for hassle-free cleaning.

For quick sharpening anywhere, these tools run on a rechargeable battery. Press your blade against the rotating abrasive belt for a razor-sharp edge. All include a guide that slides to four different angles—you can remove it to make space for larger blades. There's also a slot for manually sharpening both straight and serrated blades.

Adjustable-Angle Electric Scissors Sharpeners

Clamp and position scissors for razor-sharp edges with minimal effort. These tools have an adjustable arm that angles blades against the rotating wheels. One wheel sharpens, and the other buffs away burrs to leave a polished edge. Sharpeners work with straight and zigzag blades (also known as pinking shears) up to 14" long. Clean the abrasive wheel with included dressing stick.

Blade Sharpener Sets


	Shown in Use

A collection of stones for all your sharpening jobs, from repairing rough edges to adding razor-sharp finishes. A blade holder clamps around your knife to hold it steady as you sharpen. No need to eyeball the sharpening angle—hook the guide rod into the slots on the blade holder to position the stone at four angles. To quickly sharpen the other side of the blade edge, flip the holder over without unclamping the blade.

Carbide Abrasive—For coarse sharpening, carbide aggressively removes material to form a new edge.

Diamond Abrasive—Our hardest abrasive. Diamond can sharpen any blade material, even hardened steel.

Tungsten Steel Abrasive—An affordable option that's great for touch-ups on somewhat sharp blades. Since it's softer than carbide, tungsten steel removes less material than carbide for more control. However, this also means it dulls more quickly.

Ceramic Abrasive—For use after coarse sharpening, ceramic refines and polishes your blade’s edge. You can also use ceramic to touch up blades that are still somewhat sharp.

Water-Cooled Electric Blade Sharpeners

Run at high speeds to breeze through sharpening jobs with precision. The sharpening wheel spins through a cooling water bath, so high-speed cutting won’t burn, bend, or weaken your blade edge. The water also washes away debris and traps airborne dust particles to keep the wheel abrasive and your workspace clean. Secure the included jig for chisels and planes into the support arm. Make precise adjustments to lock in your sharpening angle for consistent, accurate cuts every time. Additional jigs (sold separately) help you sharpen scissors, drill bits, axes, and more. Made of cast components, these sharpeners are built to last.

When you need finer or coarser cuts, the wheel dresser grades the wheel down to a 1000 grit surface and roughs it back up to a 220 grit surface. Stop anywhere in between for an intermediate grit. The dresser only removes a tiny amount of material, so it won’t shorten the life of the wheel. If the wheel becomes uneven over time, return it to shape with the truing tool.

The leather wheel perfects your edge by removing burs left from the aluminum oxide wheel. Soften the leather with honing oil and honing compound before using it on your blade.

Strike your sharpening stone with your blade at the correct angle for a razor-sharp edge—every time. These guides include multiple angle options. Use a lower angle for a sharper blade and a higher angle for a more durable blade.

2 Sharpening Angles—A wooden base holds the included sharpening stones at two different angles. Draw your blade down either stone to sharpen.

4 Sharpening Angles—A magnetic base secures these guides directly to your sharpening stone. The four-sided base offers four different sharpening angles. Press your blade against the guide as you strike the stone to maintain the angle.
