Main Benefits

Its interchangeable disc system supports compatible optional sharpening and whetstone discs. Choose the finish you prefer without changing the core Pro sharpening system.

Which knives work with Tumbler Pro?

Tumbler Pro works with most straight-edge steel kitchen knives and many outdoor knives that can be held securely by the magnetic holder.

It is not designed for serrated knives, ceramic knives or scissors. Check the knife maker's recommended sharpening angle and instructions before sharpening specialty or single-bevel knives. For smaller blades, compare Tumbler Mini.

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?

Tumbler Pro rolling knife sharpener with a four-layer diamond sharpening disc, EdgeBoost ceramic honing disc and the standard 15°/20° magnetic knife holder. Optional whetstone discs and other accessories are sold separately unless included in the selected set.

Frequently Asked Questions

Why should I pick the Tumbler Pro instead of the Original Tumbler?

Choose Tumbler Pro if you want a four-layer diamond sharpening disc, EdgeBoost ceramic honing and an interchangeable disc system with compatible optional upgrades. Tumbler Original uses diamond sharpening and a stainless steel honing surface for straightforward everyday sharpening. Both standard holders offer 15° and 20° settings.

Can I sharpen specialty and high-end knives with the Tumbler Pro?

Many straight-edge steel knives can be sharpened with Tumbler Pro when they fit securely on the magnetic holder. Follow the knife maker's recommended angle and instructions. Do not assume that 15° or 20° suits every specialty or single-bevel knife, or choose an angle from a Damascus pattern alone. Tumbler Pro is not designed for serrated knives, ceramic knives or scissors.

How does the Tumbler Pro’s removable disc system work?

Tumbler Pro includes diamond sharpening and ceramic honing discs. Its interchangeable disc system supports optional 3000/6000 grit Whetstone Discs for further finishing and the #150 Coarse Diamond Disc for faster material removal. These optional discs fit qualifying Pro models purchased after June 1, 2025, identified by a hex recess above the screw threads; they do not fit Original or earlier Pro models. Check product compatibility before ordering.

What maintenance does the Tumbler Pro require?

The Tumbler Pro is designed for low-maintenance use. Simply clean the discs after each use with a dry cloth to remove any residue, and occasionally check for any debris buildup around the magnetic holder and disc area. There’s no need for oils or water with the standard sharpening and honing discs.

Can the Tumbler Pro sharpen serrated knives?

No, the Tumbler Pro, like the Original, is designed for straight-edge knives and does not support serrated knives.

Is there a satisfaction guarantee for the Tumbler Pro?

Yes! The Tumbler Pro comes with a 100% satisfaction guarantee, plus a 30-day money-back promise. It’s also backed by a warranty covering manufacturing defects, so you can purchase with confidence.
