Sharpening Stone for Pocket Knife Question?

I use a sharpening stick that is impregnated with diamond dust. When sharpening I put the edge on the stick at an angle as though I was going to try and slice a very thin layer off of the sharpening stick and then I push the edge of the knife forwards as if still trying to slice off a layer of the stick. With a diamond dust stick it does not take much to have a razor sharp edge.
