Ah, the rare yet beautiful metric roadfind.
I think I have only found 2 or 3 metric roadfinds in the past, a broken 10mm Mercedes Benz box wrench, a beautiful snap on short combo wrench in the practically-as-useless-as-english 18mm size and this:
a 15mm Stanley socket. Sort of useful for the odd 15mm crank bolt too! Found near the Aquatic center on canyon, site of many other roadfinds in los alamos, such as the superball and the right angle scale in two parts.
My tool box is filled with 3/8" sockets and combo wrenches that I have found awheel, but it is a rare bird to find a metric thingy calling your name while on the road.
More cat/bike stuff tomorrow, the new camera takes good video and macro so far so I have lots of good stuff to show you, races and rides and other.
Anyone know how to scan X-rays effectively, if so, I have a treat (not me ma, a cat.)
