I own 4 tagine of various sizes. One of the very big ones I bought in Algeria or Morocco about 10 or so years ago, and carried back to the UK in my hand luggage. It weighed a ton and I was so careful with the bag, in order to get it home in one piece.
Two or three months later, I found the very same tagine (size, maker) on sale in the kitchware section of a large department store, for about the same cost as the authentic one I'd lugged back from holiday!
I forgot to say, that strange 'chimney' on the tagine's lid is not open to the air - it is used to allow the steam to congregate and then allow it to drop back into the stew/couscous or whatever you are cooking, keeping it deliciously moist!
Another strange tool is the Scottish spurtle, used to prepare porridge. In fact, there is a competition each year, called the Golden Spurtle Award. Here's the website and there's a photograph of a woman holding said award, which will show you the shape

I also use my granny's 'girdle' - what we call a griddle. It is a large circle of metal, with a handle which folds down, which was traditionally the way we made scones and potato scones. It still makes the best drop scones (what the English call Scotch pancakes) and it must be at least 120 years old, cos it was my Granny's mum's before her!
