I haven’t done any systematic tests, but have observed the same phenomenon. I once asked about it on this forum, and was essentially told I was wrong, but a little thought experiment I used was to imagine two edges, both one-molecule thick, one at 179 degrees, and one at 1 degree (and both unsusceptible to deformation). I can’t imagine the 179-degree edge cutting the media without considerably more force than the 1-degree, so it comes down to within what range of angles do the differences become irrelevant. Thanks to your efforts here, I now have something quantitative, which I very much appreciate. I usually sharpen at 15 dps, and no matter how hard I try, can’t get below 70~80 BESS, though I can easily whittle hair when I try. Now that I have your numbers, I’ll check against them when I sharpen at other angles. Much appreciate your work here!
