Straight Razor Bevel Angle Calculating

Calculating the bevel angles on four modern straight razors produced in Solingen, Germany. The razors produced today are very much in line with what was always produced, but not as acute as the peak of acuity from the 20th. century. Be aware, of course, with extreme acuity comes extreme fragility. The meat of this video, the "crude drawing", has a very minor simplification; namely, the fact that the Germans always hone on a convex stone ever so slightly changes the bevel angle from what is shown...but it will only do so more actuely, not more obtusely. If you were honing on a concaved stone your edge would always be 'downhill' from your spine and thus your spine's contact line would be slightly closer to the edge, and on a convexed stone the same line favors to be away from the edge. Too convexed a hone, however, would result in the bevel planes themselves no longer being planes, and being little curves; thus the German way of preparing the convexed stone always keeps the slope very gradual in incline and modest in peak. You can use the basic formula, however, and the convexed stone will affect this less than 1-deg.
