I sharpen on 240 and finer, and I stopped using Klingspor belts a long time ago. For fine work and sharpening, I much prefer (and think I get better results with) structured abrasive belts, like 3M Trizact. For hogging and heavy work I've mostly gone to 3M Regalite and Cubitron.
Your results may vary, but next time you put in a belt order, I'd urge you to at least pick up one of the higher end 3M belts in the grits you use most often and see if you don't think it's worth the money. I usually get mine from Tru-Grit, Sheffield, or TKS.
Anyway, with the Trizacts, no chipping on VG-10, S30V, or anything else I've sharpened. I just got my first piece of ZDP, and haven't redone the factory edge yet, so I can't comment there. I do heavy edge resetting with a 120 grit 3M (Cubitron, I think, without being in the shop) and I haven't had any trouble there either.
The Klingspor belts are OK, but I got tired of just "OK".
