I picked up a used older Smith kit. It has a hard case vice the videos online with the zipper case, and you have to screw the guides on every time, but otherwise looks the same as the current kits. I used the kit, coarse and fine stone at 20 degrees, on my KAI cheap knife, and it made a sharp edge. I cut the heck out of an onion and a pepper. It does the cool looking paper slice on printer paper. Thinking about trying the kit on a good knife. What did I do wrong, if anything? 25 degrees? No oil next time? I was at a family dinner for Thanksgiving and was asked to save/finish a few items because lazy, unknowing, and wine doesn't get anything done. My favorite was the 15 year old wustof knives which couldn't cut the turkey because they have been washed in the washer, and never sharpened. My wife volunteered me to sharpen them. I may try the kit on family screwed up knives, or I may take them to the Sur La Table and have them do it to save me the PITA--they have a sign up they will do it cheap. I do want to make my knives better, though.
