Not on coticules. That is usually the way with JNats, but for coticules it's normally heavy slurry for the coarser work, then gradual dilution to straight water for finishing. Some coticules are much better than others though. I have one that is pretty meh and takes forever to finish with but leaves a very keen edge and one that is very very fast but when diluted to straight water still gets just as keen. Both edges are certainly shaveable though.
