I was wondering if it's common at all, and if you need a particular type of leather. My girlfriend's grandpa was a leather smith and when we cleaned out their old cabin we found roles of leather of various types. I was thinking about finding one that seemed most like a "professionally" made strop and trying to make my own. If you guys have done this, are there special things I might need to know or a tutorial online or anything, or just have at it and make it to my liking?
