That's fantastic. What is the overall width? That will determine whether you can really cut the strop shorter. I guess if you have a scrap piece of leather that you can use, try a strip that is that much shorter and see if you can comfortably strop with it, if you can, then you're good to go! Or perhaps just hold the strop up a couple inches higher and see if that is comfortable.

I really love the rustic look, you are absolutely correct with the cowboy reminiscence. I guess I should get down to my Tandy store and pick up some more leather. That looks like it was fun to make!
