I actually did try it quite some time ago with mixed results. This was a strop I'd made myself from a relatively heavy thickness of cowhide. The flesh side is pretty dry and coarse and I think with a lot of conditioning it would make a great stropping surface. But as it is now, no.Could you do it . . . for science?
My daily driver strop is one of Tony's roughout horsehides. It's soft textured and works very well.
