Today I learned about the ‘80s Casio calculator that doubles as a massive lighter.

I wanted it to be February’s Button of the Month — partly because its big honking button has an incredible click and shoots out a monster jet of flame, partly because it triples as an alarm clock (!), and partly ‘cuz it hearkens back to Casio’s original invention: a finger ring for cigarettes.

Sadly, the Casio QL-10 seems rare. Last time one hit eBay, it sold for $499. Behold history through other people’s cameras in our gallery instead:
