The other thread reminded me of something I was wondering about a while back. Here in the US we buy a metric socket set but it comes with 1/4, 3/8, 1/2, etc. drive sizes. Do metric countries have socket sets with metric drives? If so is it possible to get a true metric set here in the US? In metric countries do they buy inch sockets with metric drives? One year my dad wanted a metric measuring tape, not a combination one but one that was metric only, ended up having to order the thing.
