    For years I have used the basic Lansky 5-stone sharpener with the addition of the sapphire stone and DMT 3-tube diamond pastes for stropping, for my folding knives. And I can always got them hair popping although for some steels it took hours to get there. The spyderco Delica ZDP-189 however seemed to need even more time to sharpen. Out of frustration I bought the 120 grit and 280 grit diamonds to try out and boy are they fast and effective. On this particular knife, I'd say the diamonds work at least 10 times faster to get where I want than the base stones (granted they are a bit old and worn). I plan to buy also the 600 grit diamond. These three plus the 1000 grit and 2000 grit ceramic stones should be a good to handle any super steels I assume.

    I bought their diamond guided kit. Extra course, course, medium and fine stones. Then added the yellow ceramic and sapphire. They cut fast. Just go easy on softer steels

    yup, keep the pressure light.
    the diamond stones are noticeably heavier than the others, so I try to use the weight of the stone and not much more.

    Got the same setup. Made a leather strop by gluing a piece of leather to an old Lansky stone. My sapphire didn't come in true flat, but with some aluminum oxide, water & a sheet of glass; I got it pretty flat.

    Good idea with the leather. I may try that

    Yeah, the diamond stones are a must have for modern steels. I like using a few drops of mineral oil on my diamond stones (especially when new) as they are normally very aggressive and the oil also helps to float the metal to the top.

    the ceramic is not as hard as Vanadium so not idea for super steel with high amount of Vanadium content. They may still work, Use lightly and clean off the stones as soon as they load up, cause they'll load up fast.

    Also gritomatic makes venev bonded diamond stones for the lansky too. Though the 2000 grit venev stones have been said to have some issues iirc, think they were more coarse or something like that).
