I have used mine on various occasions, but I couldn't tell you exactly when. I found one time that if it were not for those wrenches, I would still be working on that car. I see angle wrenches the same way that I see some of the cooking utensils that my wife has. It isn't how often that you use them, but that you use them when it is called for. Some people could get along with a pair of pliers, a screwdriver, and a hammer, but most of us are not as resourceful as McGuiver. I use most of the tools in my tool box, except for the fuel filter socket that fits the early 1960's Fords and the socket for the Chrysler screwed in ball joints of the 1960's.
