Review on 🔪 THRITOP 3-in-1 Electric Knife Sharpener Tool: Effortless Sharpening for Knives, Scissors & Screwdrivers, 40W, Black by Bryan Sperling

This is a sharpener. It will leave metal powder on the surface, after you finish, be sure to clean it. It took me several attempts to master this method. Tip: Pay attention to the angle at which you position the knife. The instructions in the package were riddled with the wrong words, probably a translation issue. Be sure to read the instructions several times. Do not use the course side unless the knife is dull. I think that's how I put a notch in it. I bet a real chef will say that a whetstone is better because you can scratch your knife with sharpeners if you use it incorrectly. I like it: my knife can cut tomatoes again. Hooray!
