Have tried most systems..DMT, Sharpmaker, ceramic rods, stones,etc.
but to get shaving sharp, I keep going back to my 2x72 belt run SLOW.
If a brand new blade, on a knife I just made, 60 micron then 30 micron, then strop on leather (glued to 2"x8" wood) that is loaded with green chrome rouge...usually this gets shaving sharp edge....but may go to 15 micron 9 micron if really fine thin blade, then usually no more than 2 strokes each direction on the laether strop with green chrome rouge..sharpened one Damascus blade yesterday so sharp that while shaving arm hair, drew blood and I didn't even notice it until I saw the blood...didn't hurt at all.
To renew an exhisting edge, to get a very fine wire edge, the 30 micron lightly, then 15 or 9 micron, then the strop 2 strokes each way, 3 at most. This usually is shaving sharp again and can take under a minute to achieve.
Make sure you have a very consistant fine wire edge all along the edge, then the strop will provide a very consistant shaving edge. Inspect with magnification befor stroping and after stroping.
Stay Safe,
