How Does a Leather Strop Sharpen a Razor?

Here are the steps:

1. Hang or lay the strop flat.
2. Hold the razor at a 30-degree angle to the strop.
3. Lead with the spine, gently pull the razor towards you.
4. Flip the razor over its spine at the end of the stroke.
5. Push away, leading with the spine again. Repeat for 10-20 strokes or until the edge is polished.
