Precise and long-lasting sharpness
Tumbler resharpens blades to renew the life of your knives. Precise enough to protect the surface of Damascus knives and other artisan cutlery, it sharpens cleavers, paring knives and everything in between.
Diamond Plated Sharpening Disc
Diamonds: the hardest, most-effective sharpening stones. Remove the first layer of your knife’s edge with fine diamond abrasives. The grit size of D35 is perfect for base grinds and resharpening your knife.
Helix Disc with EdgeBoost™
Refine your knife’s edge. The proprietary stainless steel helix disc removes the burr of your knife’s edge and any leftover grinding particles after the base sharpening. The result? A finer edge for more precise cutting that preserves food’s flavors for more delicious meals.
20 and 15 degree sharpening angle
Sharpen traditional and specialty blades. With two powerful magnets to keep your knife at exactly 20° or 15°, you'll always get uniform angles over the entire cutting edge – regardless of knife size.
Our packaging makes it the ideal gift for yourself or a significant other.
