If you added one piece of electrical tape to give a thickness of 6.09mm and maintained the same grinding angle, the bevel would be 8.366mm wide. That's a .124mm difference! On something as thin as a razor we are talking about even smaller changes.
Of course, I could be wrong about this! I'm just going on my own experience

mikew said:What would you say in real terms the difference would be between a bevel set at 15 degrees and one set at 25 degrees. Of course it would look different but how would it effect shaving? After all that's the important bit right?
mikew said:Good fun indeed. My expertise really lie in knifemaking, specifically high end kitchen knives where the optimum bevel angle is 15-18 degrees per side, so not that different really.
In both cases, how thin the the blade is behind the edge is extremely important too. In other words, how thin the blade is ground before the bevel is set. That's maybe drifting off topic though....

CMOT said:Also wondering if you use tape for honing should you also use it for refreshing the edge?
