Somewhere, I have an odd knife. I don’t remember which one it is, but it might have been a frontier-style skinning knife. Or maybe not. Anyway, someone asked me what it was for.
I said, ‘It’s a fog knife.’
‘A fog knife?’
‘Yeah, you know how people say that “the fog was so thick, you could cut it with a knife”? That’s what it’s for. Say you’re out in your boat and it’re really foggy. You use the fog knife to cut chunks out of the fog so you can find your way back to port.’
I have a tendency to say things like that with a straight face, so it took a second before she was like, ‘Hey, wait a minute!’
What are your ‘special purpose tools/objects/devices’, in the style of my ‘fog knife’?
