Got tired of having to spend a couple of hours every other month to sharpen kitchen knives on a regular whetstone, so I picked up one of these after reading a lot of rave reviews

I was dubious about how well an electric sharpener would compare to a manual whetstone, but damn it makes a way sharper edge than I could ever manage in a fraction of the time. I had 4 knives that were heavily abused by my wife and her mom, and once I had the technique down it took no more than 5 minutes on each to go from rough chipped blades to the sharpest knives I've ever used. I'm sure a master sharpener could still beat the machine with high end stones, but for amateur cooks this thing is a game changer
