Silly Saturday: Torture Instrument...?!

If you're wondering what this is, I'm not too surprised. I'll start with some silly ideas as to what it could be:

Is it an instrument of torture to keep my Editor under control? - No, she's better behaved than that.

Is it a bed of nails for a doll? - No.

It's actually a home-made knee kicker. I made it many years ago (maybe more than 30, I'm not sure) from instructions in the Readers Digest DIY Manual. It's suffered a degree of abuse over the years, which is why a couple of the nails have broken off, and if I were making it again I'd modify the design a little. But it still works: I thought of blipping it today as I've been using it to re-lay some of our attic carpet which had to be lifted when the partial rewiring job was going on a few weeks ago. Oh, and then I had to lift the carpet a little further to dry it out when I forgot to close one of the radiator venting screws when I refilled the central heating system after a bit of new plumbing during the same week as the rewiring. Doh! Was that silly, or what?!

Thanks as always to admirer for hosting Silly Saturday.
