Double Ended Box Wrenches: Which End is Up?

Do you own any double open-ended wrenches with a different size on each end? Do you ever pick up the wrong end? I used to do that.

If you are interested, please see

Your comments are welcome. All of us are smarter than any one of us.


Thanks,

-Simple and easy, thanks Rick!

But lacking telekinetic powers myself, how could the O-ring by itself know and slide along the handle towards the end I want? :D

That chart is why people need the so called no skip socket or wrench sets. I believe Japan throws one more odd wrench into the line up. It is really frustrating as you end up needing a large collection of wrenches for that one odd nut.

Ricks method is interesting and could be used for both double ended box and open ended wrenches. this post reminds me though that I need to order a large wrench for my drill press.
