Well, recently, while reloading my grinder with a new disc, I happened to take a closer look at the one I was loading up and wondered what the story was behind it (perhaps being a new fan of that cable TV show "How it's Made" has piqued my curiosity). Anyway, I went ahead and finished what I was doing, but also decided to do a little investigating regarding abrasives. The following is what I learned and thought was interesting enough to share - and I hope you agree.
