There must've been an old clause in airline travel that let you take otherwise contraband items through, as long as they were "tools of the trade," because those are the words my bookbinding instructor, Maureen Duke, always uses when she talks about bringing paring knives through airport security. It stuck with me because of the smirk she used when she said the term, like it was the magic phrase that would suddenly defeat the intimidating security guys. "Tools of the trade, boys!" and she saunters through with her knives. I can picture it.
With the new academic year started, and students starting to build up their own collections of tools, I gathered my favorites.
Maybe bookbinding tools next time.
