Went got me a few goodies but this one is interesting. It's a set of bits for security screws. Manufacturers use them to keep us from taking their products apart for repairing. I needed them before and now I have it for $7.
About 25 years ago, I needed one of those security bits to open something and went to the store to buy it. The store had the one I needed but they would not sell it to me because I wasn't "authorized". I talked to the guy at work that ordered our tools and he ordered one for me.
