Where do they go?

I'm convinced there's some sort of cutlery-specific Black Hole - or other kind of gulping void - located in my house. Things vanish. For no obvious reason.
Not so long ago we had three corkscrews: two in the kitchen, one in my suitcase (for emergencies - how may times have you gone on holiday, bought a bottle of wine and found you have no way of opening it?). One of the kitchen ones broke - fair enough - then the other one disappeared. Along with the one in my suitcase. How? I hadn't taken it out - neither had Caroline - and it was there the last time I'd unpacked.
And don't start me on teaspoons! They are definitely going, one by one. We used to have a full set of six squared-off spoons that are useful for eating yoghurt and the like. Now there are two. Sometimes. Occasionally one will take a holiday for a week. To where? Neither of us has taken it.
Then last night the potato peeler took a hike. It was there last week - I remember using it. To peel spuds.
