How To Use Tumbler
INITIAL SHARPENING
The initial sharpening involves the crucial first removal of steel and establishing a consistent sharpening angle. This may take 5 – 8 minutes, depending on the condition of the blade.
Future resharpening will take less than 1 – 2 minutes.
Tips
Use a light amount of pressure! Sharpen on a stable surface such as a kitchen counter or cutting board. For taller knives support the Tumbler Rolling Sharpener with a cutting board so the sharpener is elevated to the level of the cutting edge.

Placement

2
Sharpening one side
Start with the diamond disk. Place the magnetic holder firmly onto a stable the surface and grab the Rolling Sharpener with the other hand. Roll the Tumbler along the entire cutting edge of the knife. Don’t forget the tip!
3
Sharpen The Other Side
Rotate the knife by 180° and repeat and repeat the sharpening process with the Diamond Disc so that both sides are sharpened even.
4
HONE THE EDGE FROM BOTH SIDES
Flip the Rolling Sharpener around (180°) to the Helix Honing Disc. Start the same movement process ON BOTH SIDES OF THE BLADE to remove any burr. Here you need a maximum of 6 repetitions for each side.
5
REMOVE ABRASIVE DUST
After sharpening, clean the knife with
a cleaning cloth. You will notice the dark abrasive dust that the diamond disc created. This is a sign that you have achieved an effective result with the Tumbler.

IMPORTANT: CHECK FOR A BURR
Check with your fingernail whether a burr can still be felt on the cutting edge. If so, repeat the sharpening and honing process until no more burr can be felt. This is how you achieve maximum sharpness!

Tumbler is the smartest way to sharpen your knives. It’s highly intuitive and brings quick results. Attach any metal knife to the magnetic knife sharpener and use the Tumbler rolling sharpener to sharpen any of your household or kitchen knife by gliding it along the edge of the blade.
The industrial diamonds used by Tumbler are the optimal material for restoring knife blades of any hardness to an optimal basic sharpness. With the coarse diamond grinding wheel you resharpen your knives in the first step and achieve a very good grinding result. After coarse sharpening with the diamond disc, the cutting edge gets a fine finish with the stainless steel honing wheel and the last burr on the cutting edge is smoothed out. Only a few movements to the front and back are needed here to achieve the desired result.
Tumbler works with most knives, including but not limited to kitchen knives, cleavers, most hunting knives with a smooth edge, folding knives with a smooth edge. Blades that are not suitable for sharpening with the Tumbler are those at bread knives and scissors.
