I have only stropped 3 times.

I watched many videos and I do it relatively slowly on my "Poorman's Strop" from Whipped Dog. I do it on my counter. I got this strop because I was warned that I would likely ruin one. I even got a back up.

But so far, I dont think I can see how I would cut it. I'm not saying this to brag (3 times lol) but I'm asking what are the common ways that folks ruin a strop so that I can proactively avoid making those mistakes?

Thanks.
