The IRuiYinGo Electric Knife Sharpener is a small USB-rechargeable sharpener that runs a knife through a slot with a motorized stone. It is aimed at home cooks who want a quick touch-up without learning whetstone technique. Against manual pull-through sharpeners it saves effort; against full-size electric sharpeners with multiple stages it removes less metal control and offers fewer grits. Its 3.6-out-of-5 rating from 82 buyers suggests a mixed reception, with complaints about build and results on harder steels.

Buyers are split: some find it a convenient way to revive dull kitchen knives quickly, while others report weak sharpening and a light, plasticky build. The 3.6 average reflects that inconsistency.
The IRuiYinGo Electric Knife Sharpener is a fully automatic kitchen sharpener that charges over USB. It is made to restore the edge on dull knives quickly.
To use it, place the knife in the slot and the sharpener does the work. A motor drives the sharpening for a consistent process, and durable sharpening stones put the edge on the blade. It can be used on kitchen knives and outdoor blades.
