Not sure if this has been posted - but I've noticed quite a catch-22 in learning the straight razor. I cut myself a few times originally, then no problem for weeks. Then (I think) I'm getting better at stropping. I went for weeks with no knicks and now that I'm getting better at stropping (plus CrOx) I think I've gotten to where I've made my razor way sharper than before. I feel like I'm learning over again as I get better at stropping.
