INTRODUCING THE NEW TUMBLER PRO BUNDLE

Take your knife sharpening experience to the next level with this kit that includes our Pro-Level sharpener and two whetstone discs that refine edges to razor sharpness — now in a convenient bundle.

Three years later, it’s trusted in kitchens and at barbecues across the country.

Frequently Asked QUestions

Tumbler offers a unique blend of simplicity, precision, and professional-grade sharpness that outperforms traditional sharpening tools and services:

Versus a Honing Rod
Honing rods help maintain an edge by realigning the blade, but they don’t actually sharpen. Tumbler’s diamond-coated disc provides true sharpening, restoring your knife’s edge to like-new sharpness.

Versus Pull-Through Sharpeners
While pull-through sharpeners are quick, they can strip away excessive material, reducing blade lifespan. Tumbler’s rolling action and magnetic holder provide a controlled, consistent angle, giving you effective sharpening without excess wear.

Versus Whetstones
Whetstones deliver a precise edge but are time-intensive and tricky to master. Tumbler combines the accuracy of a whetstone with the ease of pre-set angles, offering a professional finish in minutes.

Versus Professional Sharpening Services
Professional sharpening can deliver good results, but it requires time and expense—and you’re left without your knives during the service. Tumbler allows you to achieve comparable, pro-grade sharpness at home anytime, with no wait

The Tumbler Rolling Sharpener™ redefines the way you sharpen knives with its effortless rolling action and precision-focused design. Using a magnetic holder to align your blade at the perfect angle (15° or 20°), the Tumbler rolls across the knife’s edge with a diamond-coated sharpening disc, restoring factory-sharp knives in minutes.

Tumbler is designed to sharpen kitchen knives, outdoor knives, and even specialty blades like Damascus or high-carbon steel. It’s versatile enough for all your knife needs.
