Description Of The Tumbler Rolling Knife Sharpener
Quality knives are expensive, and keeping them sharp can be challenging. The Tumbler rolling knife sharpener helps your knives stay sharp for a long time.
It uses diamonds, the hardest material, to sharpen your knife’s edge quickly.
It has a special disc to edge quickly and another disc to smooth the knife’s edge after sharpening.
How It Works
- Choose Your Angle: Select either a 15 or 20-degree angle for sharpening.
- Secure Your Blade: Use the magnetic knife holder to hold your blade in place.
- Sharpen: Roll the sharpening disc back and forth along the knife edge until it is sharp.
- Smooth the Edge: Use the stainless steel disc to remove any rough spots and finish the edge.
Sharpening With The Tumbler
The Tumbler is an easy and effective way to sharpen your knives. To use it, attach any metal knife to the magnetic holder.
Then, glide the Tumbler rolling sharpener along the edge of the blade to sharpen it.
Using The Diamond Disc And Stainless Steel Honing Disc
The Tumbler uses industrial diamonds, which are great for sharpening any knife blade.
First, use the coarse diamond disc to sharpen the knife and restore its edge.
Then, use the stainless steel honing disc to smooth out the edge and remove any burrs.
Just a few back-and-forth movements with each disc are needed to get a sharp and smooth edge.
Choosing Between 15° And 20° Sharpening Angles
The 20-degree angle is sturdier, making it suitable for most Western knives, which are often made of softer steel.
The 15-degree angle is sharper but might need more frequent sharpening, especially for softer Western knives.
Japanese knives, made from harder steel, can hold the 15-degree edge longer.
Changing a knife’s angle from 20 degrees to 15 degrees will make it sharper but will also mean you’ll need to sharpen it more often and might remove more metal over time.
