Update: this thing is an old-fashioned crimper for can lids. After many serious and no-so-serious guesses, ladybugs finally had the correct answer. The funniest answer was from Randall, who said,

This is a clock unwinder. In Victorian time it was feared that a clock left wound over the new year eve would cause infertility. The first thing that Victorian men would do on the New Years day was get out of bed to wind and set the clock. THe would then go back to bed and test for infertility. As a result of this pratice the clock unwinder was considered a very risque' item great care was taken to keep it stored descreetly. You can still find them in secret cubbyholes under staircases in older homes, covered with dust, biding their time.

That's good for a t-shirt, too! See the answers to all the mystery items of the week at the What Is It? blog.
