Interesting Secondary Tools

IIRC that "skate key" was used to turn a valve on when cars had acetylene lamps instead of electric lights.--KV

Entirely possible, but I believe Queen's intent with that tool was to adjust old-style rollerskates like these (note the square-headed bolt):

Yes, that is what a skate key is for. My mother always carried a skate key with her when she was a kid.

I guess since it says skate key on the box I am obviously wrong. DUH! Ive seen old pocket knives that had a similar key used to turn on the "Presto-lite", [I think was the name], acetylene lights on early autos before electric lights.--KV
