From the brand

Ultimate Precision & Sharpness: Any serious chef knows quality knives are expensive. Keep yours cutting like new for much, much longer with the Tumbler Pro rolling knife sharpener. Engineered for those who demand more, the Pro is an essential tool for professional kitchens and serious home chefs alike.
Premium 4-Layer Diamond Sharpening Disc: The 4-layer sharpening disc is plated with nature’s hardest, most-effective sharpening stones: diamonds. The layered diamonds, nickel & stainless steel effortlessly remove the first layer of your knife’s edge while restoring sharpness.
A Finer Edge: A proprietary ceramic honing disc on the other end of the kitchen knife sharpener removes the burr of your knife’s edge after the base sharpening. The result? A finer edge for more precise cutting that makes all kitchen tasks easier.
Removable Disc System: With advanced removable disc technology, the Tumbler Pro knife sharpening kit offers a customizable sharpening experience. Optional whetstones (purchased separately) allow for further edge refinement for a truly professional sharpness.
Great for Gifting: The Tumbler Pro is the perfect present for culinary enthusiasts. Each kit comes with the Tumbler Pro sharpener, which features an ultra-durable resin body, & the magnetic knife holder.
