Thread: Harshness and Final Bevel Shape

My last venture into high grit pyramids got me thinking. The effect of going back to the slurried Nat without tape reduced the angle of the microbevel of the 30k. The slurry reduced the amount of metal supporting the edge and in effect made the bevel flatter reducing the micro bevel angle. In other words, a certain amount of convex bevel shape is related to the smoothness factor we feel while shaving. Supporting this new idea, I took a harsh high grit pyramid bevel and reworked it with a micro bevel on a 16k, then one more piece of tape to make another micro with the 30k. Result was a smooth shave once again. Also, supporting the importance of having some degree of convex shape are some of the best razor honers using diamond spray on felt to finish off their bevels. Some of the naturals may also be creating a degree of convex bevel do to their slurries.
It now makes some sense to me that a perfect edge with no convex shape interacts with the skin giving a harsh shave. A convex shape, by whatever means created, makes contact with the skin at the same time as the edge supporting it and giving a smooth shave. Does that make sense?
