I pulled one out of the BOC years ago, clueless. Not understanding what it was... I was informed, just in time to
NOTthrow it away. I had intended to return it to the box. But I moved a few years ago, and it's come in handy on many occasions, the old bottle opener got left behind.
I don't want to blurt out the wrong name, but he who created it has my thanks!
It's also a good conversation starter
Cheers, Eric
