The Pro Rolling Knife Sharpener is a rolling-style sharpener that runs the blade over a spinning diamond disc, then a ceramic disc for honing. Its 4-layer diamond disc cuts faster than single-layer discs, and the heavier build keeps the roll steadier for more control. The discs swap out, so you can add optional whetstones for a finer edge. It suits home cooks who want a repeatable sharp edge without learning freehand whetstone technique; it is not a substitute for a full guided stone system on very hard steels.

Owners rate it highly and mostly praise how quickly it puts a usable edge on kitchen knives with little effort. Complaints center on the diamond disc wearing down and on the extra cost of optional stones.
The Pro Rolling Knife Sharpener is an upgraded rolling sharpener built to sharpen knives and refine their edges. It has a heavier build than the earlier version, which gives more control while sharpening.
It uses a 4-layer DNC diamond disc for sharpening, and the store says it is faster, smoother and longer lasting. An EdgeBoost™ ceramic disc then hones the blade for a finer finish.
The discs can be swapped. Optional whetstones can be added for further edge refinement.
