It seems odd that anyone growing up in the last four decades is so thoroughly unacquainted with many everyday items that were commonplace in my childhood. Or at least with the words that described them.
Ask someone below the age of 40 what a skate key is, and you'll be met with a bovine stare. Try as you might to describe it, they won't have a clue. You'll get much the same reaction to "valise," the word commonly used to refer to a small suitcase in my childhood during the 1950s. But--curiously--"skate key" and "valise" puzzle recent generations in different ways: skate keys no longer exist, while "valises" are merely called by another name.
