Just had an electric dick sharpener brought for the kitchen by the bosses, It's the 150 model shown here https://www.dick.de/en/tools-for-ch...rs-75-rs-150-duo-grinding-and-honing-machines I am really reluctant to use it. I carry a mixed roll of knifes, various ones that I have found I like in my short years in the Kitchen from Mac, Henckels, Dick, Vic, and Global. Oh and Wusthof and always use a steel to sharpen them. The machine itself looks the real deal but I'm afraid to put say my 8" Mac chefs knife on there in case it becomes unusable. Has anyone here used one before and if so do you have any tips? I have a Gloabl filleting knife that I found in the back of my home kitchen drawer a few weeks back I was going to use in it first. I figured as I forgot I had it, if it does get ruined then so be it. Also my wife has been using it as a screwdriver when I'm at work (I know) so I've had to straighten the tip of it out so it's far from good at the minute!
