I think at that point you are only adding less that .001 degrees of tilt to the blade increasing the taper to 17.001 or something like that.

Is that what you are saying?

Edit: After posting your other posts appeared. A 5/8 razor = .625 removing a third of that .3/.625 = .48. .625-.48 = .145 which is equal to taking a 5/8" razor to between a 2/8 and 1/8. I would argue that the razor would be useless at about .25 of loss instead of .3 of loss.

According to your math, 0.48 is 1/3 of 0.625. Can't be bothered doing the math right now, but you may want to recalculate that one. 1/3 of .625 = 0.3 * 0.625.
Edit: That makes me sound like a tool, when in actual fact, I'm just drinking a lot.

I get the point of the original post though. What the actual angles are, is not important. You have to grind away a lot of steel from the edge in order to make any significant difference to the angle at the edge. I think you may of actually converted me with your math. I was always of the opinion that the tape must make a difference, but now it is obvious to me that the difference is miniscule.
