[This review was collected as part of a promotion.] This knife sharpener is a great tool in the kitchen. I've always been really frustrated with the dull knives but didn't want to commit to the sharpening stones. This tool came in handy since it's really easy to use, you just need to glide the knife back and forward. The rubber bottom also provides a great grip so you don't slip and cut yourself. A few things you want to be careful about is that you should sharpen the knife when it's dry, or else it might leave some rust like in the image I took. It's also a little bit hard to sharpen the tip of the knife, as it tends to go out off the glider, so be careful with that. But overall, it's a good tool to sharpen knives and it does its job.. Trin.
