The windshield wiper move might not be such a great idea on this new strop. On a flat table the surface is as flat as the razor. Hanging gives you that drop that just might be enough to put to much pressure on the tip of a square point. Kind of like if a woman in heels steps on your toe. All the weight is in a 1/2 inch dia. and feels more like a rod going through your foot. My point is you have everything pushing on that point and being harder and those little gaps it's more like pounding than gliding across the surface. It's wide enough go at a 90 and take some of that pressure off the tip.
