Don’t know what else one would want in a knife sharpener. Can’t find enough knives to sharpen. I really appreciate a product that works better than you expected and with less effort than anticipated. Had to wait on it, but the aluminum base is great. It allows me to use this in my office on my desk rather than in a workshop. “I Made Beer” folks were great to work with. Never seemed irritated with my update calls. Can’t say enough good things about my experience.
