Key Features of the Tumbler Diamond Rolling Knife Sharpener Starter Set

The Tumbler Diamond Rolling Knife Sharpener Starter Set packs some impressive features that make knife sharpening a breeze. This set stands out with its unique rolling system and diamond discs that work together to create razor-sharp edges on your blades.

Rolling sharpening system with diamond discs

Sharpening your knives just got quicker—and a whole lot easier. With this rolling sharpener, you simply glide the blade through, letting the diamond disc handle the tough work. Its D35 diamond disc matches a 100-grit stone, yet it takes way less effort than traditional sharpening methods.

Built with nickel and stainless steel, the disc stays durable even after years of repeated use.

Cooking enthusiasts will love the stainless steel helix side, which delivers a precise, finer knife edge. This sharp edge actually improves flavors, as cleaner cuts help ingredients stay fresh and tasty.

While standard sharpeners often demand frequent replacement discs, this rolling system works continuously without extra costs. Thanks to its smooth rolling motion, you’ll likely sharpen your knives more regularly—keeping blades razor-sharp and ready for action at every meal.

Magnetic knife holder with 15° and 20° angle options

The Tumbler Knife Sharpener comes with a magnetic holder that gives your blades two ideal sharpening angles. You can lock your knife at 20° for tougher kitchen tasks, creating a reliable edge perfect for daily cooking chores.

Most basic home cooking relies on this durable setting. Need finer control and precise cutting? Just switch over to the 15° angle, ideal for high-quality knives and delicate slicing tasks.

Strong built-in magnets grip your blade securely in place, preventing slips that might ruin your knife.

The right angle makes all the difference between a knife that simply cuts and one that slices with precision.

This magnetic angle system removes any guesswork from blade care. Even if you’re no professional, your knives come out feeling sharp and precise. Unlike freehand sharpening—which often causes changes in angle—this holder maintains the exact angle from start to finish.

Your knives stay sharper, perform better during use, and last longer over time. And if you’re serious about specialized knife maintenance, you might like the KNIFE HOLDER PRO model—it offers additional angles at 10°, 12°, 17°, and 25° for very precise blade care.

This sharpener tackles both stainless steel and carbon steel blades without trouble. Higher-end Japanese brands like Shun, Miyabi, and Global come out incredibly sharp. German favorites like Wüsthof and Zwilling J.A. Henckels also respond perfectly well. Even American-made Cutco and Lamson knives sharpen up quickly using its diamond discs.

You’ll see fast results even on dull, worn-down edges. There’s no learning curve here—all knife types sharpen using a straightforward rolling technique. Just set the correct angle (15° for Japanese blades and 20° for Western styles), gently roll the tool across the edge, and that’s it.

It’s perfect for anyone who doesn’t spend much time sharpening knives at home. One small catch though—this sharpener doesn’t handle serrated blades or scissors. But for regular knives, those diamond discs quickly get them sharp again, without taking off excess metal.
