Bests & Worsts Reviews from Amazon

We don't have super high quality knives, and while we would like to purchase a $500 set of knives, it's not in our current plans. So I purchased this, after reading reviews in cooking magazines and Wirecutter, and pulled out all of our knives to sharpen. This comes with a warning: Your knives will be sharper than before so be careful. Yeah, yeah, great marketing. I get it, it takes your normal 20 degree edges for less expensive knives and sharpens them to 15 degrees. Fine, I just want to be able to cut a tomato instead of tearing it. Well, pay attention to the warning. I took a knife after sharpening it with this, held a tomato in my hand (I know, stupid sign on my head) and cut it. The knife went through it so smoothly and quickly and easily I didn't even notice it kept going into my ring finger. Even then, it was sharp enough I didn't even really feel the cut in my finger at first, I just notice a line and blood! This sharpener, if you follow the instructions, will truly make your knives SHARP. Sharp enough that I've cut my hand three times because I'm not used to having to be as careful as you have to be with REALLY sharp knives. We converted a set of relatively inexpensive Cuisinart knives into a very effective knife set. No, they aren't a $600 set of knives now but I wouldn't want them any sharper! Exceeded my expectations.
