Great work Mike, you're really getting the hang of it. I agree with Eagle, I do sharpen on the grinder (except the skew) but then I further refine the edge with a little DMT diamond card. I think that you saw it when I sharpened your plane iron. That will put the final edge on your chisels. The skew should be sharped like a bench chisel on a stone to keep the flat bevel.
