I'm not nearly the sharpener that cotedupy is but I've found deburring on cotis to be easy with just edge leading strokes and as little pressure as you can manage. Wash off slurry and use water, just do a pass, flip sides, repeat a few times. I cut a paper towel to help show any problem areas that need a bit more touch up, and @captaincaed 's method of putting a paper towel or tissue over the blade to help feel small burrs as your run your fingernail along edge has been exceedingly helpful.That is an amazing edge! I've never seen a knife cut paper towel so easily! May I ask what your deburring method is and any tips you might have?
