I used a skew today to do a pen, after I modified it. The edge was curved, I sharpened it on my water stones, I also rounded the bottom of the chisel, to make it slide easier along the tool rest. That made a huge difference. Those plus adjusting my tool rest, was amazing how much better the pen came out vs. using a gouge. I did rough the pen out with a gouge though. I think I'll get me a fine diamond hone like Alan used, to touch up the edge between turnings, takes too long using the water stones.
