I suck at sharpening this steel. Plain and simple. I don't know why, I just know I do. There is a thread in the general forum on this steel (https://www.bladeforums.com/threads/zdp-189-and-cowry-x-overrated-or-super-steel.1703472/ ) and it just got me thinking about it again. I only have one example and that is a Delica that came from the factory with a terrible grind. I can grind the steel but I can never seem to get the apex right. I've used my KME and free hand. Diamond, SiC, or AlO, I just don't seem to get it. I can sharpen the popular "S" series of steels but this one eludes me. I've always thought that maybe it is because I'm so heavily reliant on burr feel and I really never feel one on this knife. But I don't know if I believe that or I just need something to tell myself. I mean, S90V doesn't exactly burr up like 440A! So yeah, I don't know... I know people say it is so easy to sharpen but man it sure has kicked my backside. What say you all? Do you struggle with it? How do you like to sharpen it?
