I'm looking into getting a set of hex keys, mainly for working on bicycles. I noticed that some have the ball end on one side. What is so special about that design? Thanks.
They are supposed to allow you to get the bolt loose even if you can't get a straight shot at the bolt. My experiance with them is that the ball breaks off in the bolt which becomes a big problem.
If it's for bicycles, then I doubt you'll use enough torque to break the ball ends off. And they may turn out handy to have.
Of course, I have the not ball end ones, and the grass is always greener on the other side.

I've never needed the ball end. In fact, I don't own a single ball end hex key.
