So here's the story my friend put a decent chip in the blade of his razor, I had to bread knife it across a DMT coarse. It got the chip out but I only had a yellow coticule at the time. I found out this coticule is a fast cutter but not coarse enough to reset a serious bevel. It is useful for a bevel that is almost there, not a serious repair. After about 5 hours of using heavy slurry and well over 1000 strokes I finally gave up on it. I ordered a 440/1000 grit water stone off of amazon.ca. I can't be more happy no more messing around with my coticule until the later stages. So now the tip and the middle of the blade are shaving arm hair easily but the heel is having troubles. I do not want to progress to the next steps until the heel catches up with the rest of the blade. I want the bevel to be completely set before I progress. Does anyone have any tips? It would be much appreciated. I don't know whether to keep giving it strokes or drop down to the 440... I highly don't want to have to drop down unless I have to. Thanks guys.
