Hi Knife,

Good drawing! You're right about the spine acting as a honing guide. Someday you'll hone an old full wedge and that's where you really have to work hard to keep a narrow bevel.

Your drawing looks exactly like my edges would look if I hadn't gotten my heavy-handed return stroke corrected. Even the same side of the blade is worn.

I'm not sure bevel depth has any effect on stropping; in stropping most of the friction is from the spine against the leather and the shaving edge just follows along for the ride. At the edge, the strop surface snags, straightens, and smooths the little dings left from collisions with hairs. That's just my intuitive understanding, and intuition may well fail out at that microscopic little bit of the world.
