    For the Work Sharp there is a diamond belt (its 1500 grit i think) especially for ceramic knives. Unfortunatelly i dont have a ceramic knife nor this specific belt. But im curious if this would work.
    Apart from that you need a shallow angle (~25°?!) to avoid chipping, the apex needs more stability.
    But you did a very good job in my opinion!

    I’ve sharpened a couple of these on my fixed angle system at 18 to 20° and to begin with seemed to be doing ok, then when progressing towards the finer grits (800grit upwards) I got a little frustrated because of fresh chipping. It dawned on me that my courser diamond plates were pretty worn and my finer were brand new and so I switched to a worn out set and got pretty good results thereafter, I did have to step back a few steps to get rid of the fresh chips though. I finished the edge with some homemade 8,000 grit diamond past on leather and got it semi-shaving sharp, as in it removed hair but I could feel it tug a tiny bit first. The angle you sharpened at seemed a lot lower than mine and may have contributed to a more fragile edge.

      I'm really thinking that (epoxy) bonded diamond stones may be the way to go with ceramic blades. Will update as soon as I have a chance to try them out.

      I agree, I have the diamonds and epoxy resin and I'm gonna try making my own before I have to resort to selling a kidney to buy a set.

    That surprising given ceramic blades are a pain to sharpen

    dont you need to use diamond to sharpen ceramic?

      You definitely need to use something hard, since ceramic is so hard. I was using a CBN wheel. CBN is short for Cubic Boron Nitride, which is the second hardest material on earth -- just behind diamond. For knife sharpening, including ceramics, there's no real difference between diamond and CBN. The only time CBN vs diamond really matters is in high-speed grinding applications, where CBN is the far better choice due to its superior inertness at high temperatures.

      @@BladeLabMiami i was def thinking that maybe the cbn was not quite hard enough or something like that but hearing this im wondering if heat is the key? i would love to see inside one of the factorys and see what they use and how they put that factory edge on there

      @@uPimppi I'd be really interested in to see how the factories sharpen these things, too.
