Are you crying??? There's no crying in straight shaving!!

No expert, me, but I can say that I messed my blade up when learning because of poor stropping. It's not uncommon I think. Is it possible for you to describe your stropping method? I agree it sounds like the edge got messed up on the strop somehow.

How much pressure did you put on the blade while stropping?
Was there a lot of sagging of the strop itself?

I can't tell you how to fix the blade unfortunately. I think you might want to send it back to Lynn to have it fixed and focus on stropping technique because if that's the problem, you'll always have it unless you learn better technique on the strop.
