I’ve been using a Lansky since the early 90’s and upgraded to the diamond version at some point many years ago. Last year I bought a Chef’s Choice 2100 sharpener mainly for kitchen knives, and boy howdy was that a costly mistake. The cooling fan on the motor broke, and they basically told me I was chit out of luck. They won’t fix it and don’t sell parts. It still works, and I’m planning to use the thing until the motor burns up and chunk it.
