OK, we all know that the coticule edge requires basically 60/60 linen/leather for peak performance. Has anyone a reason for this. Even with knife sharpening, if normal pressure is used to finish, though it is very rapid, it requires stropping to reach really sharp, but only less than a dozen or so laps and on just about any surface. I test a knife with paper, usually magazine stock, and prior to stropping six or seven tims it will cut, but drag. Afterward it absolutely glides through. I have to use many very light strokes to make up for stropping. A "Moon Stone" (ceramic) was the same way, and a Japanese waterhone is not. Any theories?
