I sure wouldn't want to disagree with you Mr Walt (my brother's name), but I'd have to think all tools are dumb.
And deaf.
And blind. haha
I'd have to think that most, if not all tools, are conceived in the minds of very intelligent people. And the most of those not while setting at a desk or drawing board, but while under a hood or vehicle, or leaning across the machine they were made to repair, by the person doing that repair.
It seems this thread has taken a very sharp left turn away from its original title, but suppose that fact is in every ones best interest
Even though it might be more comical to hear about the time someone tried a 12 ft cheater pipe and wound up on the ground with a broke nose, don't think many would be lining up to divulge those stories
