One consideration not mentioned here is to pay attention to the thickness of the sandpaper. The backing on sandpaper can vary in thickness. Thick sandpaper = more give = rounding of the edge/bevel. Try and use the best, thin sandpaper you can find.

Also, having the paper bunch up in front of the edge is a no-no and can be caused by taping the sandpaper. For that reason I do not tape or glue the sandpaper anymore because of that problem. I just use a very flat surface, get it wet and then lay the presoaked sandpaper on top. Then hone slowly.

I have tried using 2000 grit sandpaper as a substitute for the 4K hone and frankly, it did not work for me. The 8K stone simply was not able to remove the rounding on the bevel.

Just my two cents,
