Will it work for my knives?

Tumbler sharpens most straight-edge kitchen knives and many outdoor knives. Not designed for serrated or ceramic blades.

Which angle should I use: 15° or 20°?

Use the knife manufacturer's recommended sharpening angle whenever available. The standard Tumbler Original and Pro magnetic holders offer 15° and 20° settings.

A narrower angle produces a finer edge; a wider angle generally favors durability. Do not choose an angle from the knife's country of origin or Damascus pattern alone.

Knife Holder Pro offers additional fixed-angle options. For compatible newer Tumbler Pro models, the optional #150 Coarse Diamond Disc removes material faster during repair or angle changes; it does not add angle settings. Check disc compatibility before ordering.

What's included?

Two Tumbler Original rolling knife sharpeners with magnetic knife holders. Each Original sharpener has a diamond sharpening disc and stainless steel honing surface.

Which angle should I use: 15° or 20°?

The 20° angle provides a sturdy, long-lasting edge, ideal for everyday kitchen tasks and outdoor use. This angle sharpens quickly, keeping your knife ready for tougher jobs. The 15° angle is designed for precision, offering a finer edge suited to knives like Damascus or high-quality carbon steel, perfect for detailed, delicate cuts. Here’s a quick guide:

20° Angle
(Robust & Durable Edges)

• Western kitchen knives (e.g., chef’s knives, utility knives)
• Everyday stainless steel knives
• Outdoor and survival knives
• Pocket knives
• Hunting knives

15° Angle
(Precision & Fine Edges)

• Japanese kitchen knives (e.g., santoku, nakiri)
• High-quality carbon steel knives
• Damascus steel blades
• Fillet knives
• Specialty or delicate knives needing a sharper, thinner edge

These recommendations are general guidelines; check your knife’s specific manufacturer recommendations when possible.

How is Tumbler different from other sharpeners?

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
