I made a dumb and costly mistake today that I though I'd share with other newbies like me, so it won't happen to them:
I had my strop hanging on a hook that wasn't fully dosed up like a circle. It was a strong hook but the ring on the strop climbed up during stropping and came off the hook and bam! It flew toward the razor an put two nasty dings in the blade edge.
Always make sure your strop can't come loose until you want it to.
Hope this helps someone else.
