If you have a ceramic fine stone that can be used on the chisel after you have used the fine diamond
one. It will polish and give it that extra superior ability. The best edge on a chisel in my opinion is very fine with a very smooth edge.
Another tip when you do maintenance on the awl is to make sure that you avoid touching the tip. When you follow the edge and flat side just make sure to stop
when you approach the very end, if you slip the tip could be rounded. If you follow my guide the tip will automatically become pointy and sharp.
