Thanks Thomas! I actually bought one of these recently, but haven't used it yet. It was suggested to me since I had a blade that needed the edge refreshed. I think it would also be a little easier for newer people to learn on than a hanging strop which I currently use (and need to fix a few tiny nicks in ). As you said it is a great deal for something that doesn't have to be dedicated to one material/paste/spray and is easy to replace pieces on if you ruin one.
