I have been straight-razor shaving for several years. I maintain my own edges. My collection of straights is extensive. When I choose a razor for a shave I look at my notes and usually pick a razor with a bevel angle between 16 and 18 degrees thinking I’ll get the best performance. However, I have several Koraat razors, for example, with bevel angels between 20.3 and 22.1 degrees (larger 7/8 to 8/8). I get outstanding results from those razors. Why? Opinions?
