| | |   Chrome-vanadium steel socket. This hex socket (used with a handle to tighten or loosen hex nuts) is made of steel with a small percentage of chromium and vanadium to strengthen the alloy.  For some reason nut- and bolt-related tools (socked sets, crescent wrenches, adjustable wrenches, spanners, etc) seem to have "chrome vanadium" and "Cr-V" stamped on them at a much higher rate than other tools, even though similar alloys are no doubt used for many other tools.  It's probably a historical thing.
