Review on Copco Edgekeeper 2 Stage Knife Sharpener: Serrated 🔪 Slot, 7.68-Inch, Black - A Must-Have Tool for Precision Cutting by Isabella Baez

I was intrigued by this two-stage Copco Edgekeeper knife sharpener because it's compact, simple and can be used for both regular and serrated knives. It's compact and comes with a lifetime limited warranty. As others have mentioned, it's disappointing that they didn't mark the slots. You must save the packaging information so you know which slot is which. I wish there were a little more instructions on how to use it properly. I watched some online videos to get an idea. After running the knife through the slot about 5 times, I noticed that it got a bit sharper and cutting vegetables became smoother. This wasn't groundbreaking, but should help increase the overall performance of my knives.
