Straight Razor Bevel Angle Calculation
The image above is from one of my posts on Straight Razor Place. After a period of honing the width of your razor's spine will decrease. It has been hypothesized that it decreases at a different rate than your blade width, thus changing your bevel angle if you hone without any modifications (tape). What my calculations above do is use trigonometry to help us get an approximation on what the current bevel angle is. This is helpful in some restorations where you have to modify the spine width in order to achieve a bevel angle that will shave.
If you find it difficult to measure from the edge of the honing surface you can measure the blade width. This will give you an inaccurate representation but since the range of shaving angles is broad, and your measuring equipment has tolerances too it is OK Another thing to think about when using these calculations is that they assume your bevel is exactly in the middle of your spine, which isn't always the case.
