I am new to straight razor shaving. I bought a cheap leather strop, and, of course, I’ve watched videos on proper stropping technique. When I strop my Wostenholm wedge, in the movement away from me, there is not feedback or sound of any sort. But in the movement back, there is a sort of scraping sound. I assumed it might be that I’m holding the razor in a way that the spine in scraping the strop. Sometimes, I can eliminate the sound my making sure the spine is not touching the strop, but then I’m afraid I might be dulling the edge. Any thoughts, tips?
