Thread: What should I do with the back of my leather strop?

You can use it as a pasted strop. There have been a couple of tutorials, notably one by JoshEarl, that explain things pretty well. Personally, I don't do it. I prefer a flatbed or a modular paddle rather than a hanging strop but ymmv.

If you decide to give it a go, apply whatever abrasive paste/crayon you select very sparingly. CrOx paste is a popular choice, btw.
