Do you sharpen your own knives? The key to grinding your kitchen blades perfectly lies in a number of factors, two of the most important ones being A. angle, and B. directional consistency.
The problem with most kitchen knife sharpeners is that they expect you to have a steady hand and an expert eye. The Rolling Knife Sharpener's creative rethinking of the product just circumvents the problem by making sure you don't make rookie errors.
It comes with a fool-proof design and two simple components - the knife holder, and the rolling grinder.
Rather than have you manually hold the knife at a 15° angle (which isn't really something that comes naturally to most people), the magnet-enabled knife-holder easily props up your blade at a precise 15° 18° 20° 22° angle.
All you need to do is then grab the roller and run it up and down the blade using the flat table beneath you as a rolling surface. The Roller comes with a grinding surface to sharpen the blade, and a whetting surface to smooth it out, removing any burrs. This eliminates any chances of human error because you don't need to worry about holding your knife at a precise angle, or about whether you're grinding the blade in the right direction.
Since you're not really holding the knife down to a surface, you don't need to worry about whether you're applying too much or too little pressure either.
Just run the roller up and down your blade a couple of times using both the grinding and the whetting side and your blade's just as good as it would be at the hands of an expert bladesmith.
