Sometimes What Happens In The Garage Doesn't Stay In The Garage

I had an interesting thought not to long ago. I guess I met my quota for 2006.

Anybody got a metric socket set, or a combo metric & SAE set? Is it a 1/4", 3/8" or 1/2" drive set?

Are you with me now? Why is the square driver measured in inches if it is a metric tool set? Is this just an oddity of the USA? Nope. Go ahead and check out the tool section at Amazon.co.uk. See their metrics sockets are the same as ours.

Does this strike you as odd also?
