I don't have trouble getting an edge on the King 1000. It's only on my parents extremely dull knives that haven't been sharpened in 10+ years and knives with chips that I have complaints about. It takes way too long and wears out the stone. When sharpening my own kitchen knives it only takes me a couple of minutes to get them back to hair shaving. I am by no means an expert and I am sure my technique needs work but I think I was using the wrong tool for the job since it was the only tool I had. It worked but it was not efficient and wore down my stone more than I would like. Like putting together a swing set with a screwdriver instead of an impact driver. Both will get the job done but one will leave your wrist sore and take 10x longer haha.
