Diamonds. With big amount of vanadium carbides in CPM -V steels, you need something harder then aluminum oxide (known as ceramic, sapзрire...). Silicon Carbides bit harder then Vanadium Carbides, but I diamonds they are more available - Diamonds are man best friends!

Thanks, Vassili.

I usually use Norton India stone. IMHO works well too.

So far, I've used ceramics and diamonds, both worked well.

It work till size of abrasive bigger then carbide size - this way abrasive taking off carbides as a whole, but when it around 2-3 microns then CPM start shrpening ceramic. For example Spiderco fine and ultra fine does not sharpen CPM S90V.

Thanks, Vassili.

P.S. This is what use:

I found that DMT is better then other diamond sharpening stones.
