I just got a fantastic Valet Auto Strop razor - it's one of my favorite non-straight razors! It's my first SE and it's inspiring me to look at the beautiful old GEMs. It didn't come with a strop and I've done my best to thin down some strop leather that I had around, but to no avail - I just can't shave it thin enough.

Does anyone have any idea where to find leather that is so thin it will fit through the mechanism?

Many thanks!
