Thank you. Since I have OCD dull is not in my vocabulary LOL. Therefore my Diamond rods might remove too much stock. I will use softer grit rods every week. I just knew that machine was bad news. Once I only had a $50 knife but I liked it. They were demonstrating an electric machine. I let them sharpen my knife for free. "here is your toothpick sir". I mean literally nothing left. Ruined my day. My understanding since then, and along the way gathering more knowledge was no electric. So Onion is no different. I am just saying this because you just confirmed it and I hope no one here suffers the misfortune. BTW, originally people said ZDP-189 was so hard to sharpen. I never had any problem at all. Since you are correct, do not let it get dull. I imagine reprofiling super steel is difficult at best. Chris Reeve switched to S35VN only because his tools last longer. S30V is not even anywhere near M390. It is good news I can sharpen it. I much prefer no one else touches my stuff. Always comes back ruined. One last thing, carbide? Isn't that bad news too? If not it sure makes quick work. A $5 set angle lansky sharpener would make life a lot easier. No joking, could I actually use something like that? We are talking about multi thousand dollar knives here. If I could seriously use that I would be elated. Sharpmaker is rather difficult for me honestly. I never even thought of using those but I see them everywhere. I appreciate your help.
