Just for the sake of something different, I tried one of those 90* wrenches in my hand at the local Sears - they not only don't feel right they look strange. I'm too old to change now
I have a set of Gearwrenches - they get used a lot for odds and ends. So far, two have crapped out, the 9/16 and the 5/8 plus the 1/2 is starting to be a problem by changing direction which means "Watch Out Knuckles, Blood is About to Flow".
Guess what, Sears wont replace them under warranty but expect you to save the receipt PLUS send the wrench back to their manufacturer (it says that on the package). Soooooo, off to Lowes. They'll replace 'em but only as a turn over to change direction version - which is OK too, and probably stronger.
They don't replace my Snap-on, S-K or even the clunk regular Crapsman but supplement them. They sure are handy though.
