Does the width of the blade (e.g. 11/16) change the honing angle, or is the spline thickness changed to account for that? Also, do metric countries refer to this measurement in some sort of meter derivative?
As you suggest, the spine thickness and blade width determine a sharpening angle that provides a “comfortable” shave. There is no, one, perfect geometry, but inclusive angles of 16-20 degrees are common.
As to the blade width. I don’t know what measurements came from razor manufacturers back in the day. The metric system has been around well over 200 years and has been in common use since then. Today I see vintage razors listed with blade width in both millimeters and eighths or sixteenths.
