Can you explain how you tested? Laps pressure etc…I did a test of secondary strops for their ability to bring back a worn edge. Teats were done with a Filarmonica Sub Cero with 100-135 shaves on it. I testes Kanoyama canvas (either jute or hemp), 2 linens, and cotton. Linen performed the best at bringing the worn edge back. I’m not sure that you’d see a lot of difference between them in an edge with 10-20 shaves on it.
