I can see why the machined glass would be a little more practical. IT was hard to get the sandpaper to stay still on the counter top and I ended up holding the razor at a steep angle to grind out the chip. I know this is not the right way but I thought hell, if I screw up the edge or blade it is a wapienica and I might just learn something while I do it. I believe the chip or chips are close to gone and that I can finish up the job on the norton. I also now believe I am seeing an uneven bevel. It appears that the bevel on one side is less than the bevel on the other. What should my next plan of attack be here? An aggressive pyramid? I alrady did about 40 laps on the 4k side as well as a few circles.
