Am I the only one who dislikes the ball end on the long end of the L shaped and T-Handle Allen wrenches? Most of the time you don't need it and it prevents it from standing upright as you change your hand position.
Those without the ball end are different to find.
I don't know if you're the only one, but there can't be many of you. I consider the ball end to be essential.
I mostly work on motorcycles, and you would not believe how often I need that ball end. I have ball end L-keys as well as short and long bit sockets, and they all get used very regularly. Motorcycle engineers just LOVE stacking stuff in the way of other stuff. Sometimes it's just faster and easier, sometimes it's literally the only way to reach something, sometimes you can save yourself hours if you can reach more fasteners without disassembly.
For example, a long 4mm ball end is the absolute cat's *** for quickly and easily reaching fairing fasteners.
If you're working on machinery where the socket head fasteners are more easily accessible, then yeah, I can see where the ball ends can be annoying and unnecessary.
I also have a set of Bondhus ball end drivers with a little plastic patch that holds the fastener. Fantastic for getting screws started in tight spaces. Wiha also makes something called the "magic ring" fastener retainer.
Oh, and don't forget the style with an extra-short short end, very often needed when stuff is too close to other stuff...
Hex fasteners are one area where the only answer to "which tool?" is "YES, ALL THE TOOLS!"
