@Clay S, I don't see how that convexes the strop at all. The strop normally attaches to the straight bar of the D.
The center of the "straight" part is tighter, because it is closer to the curved part of the "D" than the legs. Then, when the center of the curved part of the "D" is pulled, the legs will go upward. This will make a concaved Surface, then flip it over. The "D" is upside down in my photo and drawing. Just trying to explain it as shown.@Clay S, I don't see how that convexes the strop at all. The strop normally attaches to the straight bar of the D.
It is only bent upward.Ok Bluesman, so it looks like the straight part of the D is bent so it points toward the other end of the strop. Is it also bent upward?
And is there a second bent D ring at the bottom of the Strop?
And did this induce convexity all the way down the length of the Strop? Or mainly at the ends?
^^^^^ This. You can only do nothing once.I'll see how it goes first.
As I recall, Tony Miller's strops have a decorative line incised along the lengths of the strop. I wonder if that might not help to relieve the strop from cupping. Similarly, there are some old-style barber's end strops with a diamond-back incised patterning on the backside. Perhaps this too was to relieve the strop from cupping?
The decorative line is mainly that, decorative but the tool that creates it imparts a slight rounding of the corner which I feel is less likely to catch the razor and nick with a careless stroke. A sharp square edge looks nice too showing the full thickness of the leather but tends to nick easier in my opinion.
