I have a TM hard wool strop that has a hard, slightly firmer/thicker spot on it. I think I sprayed a bit too much diamond spray there, hence why it's hard. Does anyone have any recommendations for how to even it out? I thought maybe sandpaper but that would get the abrasive from the sandpaper on it. Also, I noticed that the welt has a direction to its grain, which seems to make stropping in one direction different from stropping in the other direction since one way is with the grain and the other is against. Has anyone had any problems with this? I think this has led one side of my razor to round more than the other but am not too sure since I have only stropped for a few months (less on the wool).
