OK! for a relative feel

My 5/8 Dovo Micarta has (roughly) the following dimensions:
15.875 mm from spine (where it contacts layed flat) to edge
5 mm spine width

That's going to give me an approximate bevel angle of 18.12*

If I were to tape the spine and lose 1/8" of blade, the bevel angle would go to 22.71*
If I were to tape the edge and lose 1 mm of spine width the bevel angle would go to 14.48*
