It's funny what you think of at odd moments

I own a hacksaw, or possibly a coping saw, I'm not sure what the difference is. Anyway, I've got one, in one of my old cardboard boxes. It just occurred to me today, apropos of nothing, and I dug it out just to make sure I wasn't imagining it. But I can't for the life of me remember why I bought the thing. I'm not a DIY kind of person and I'm sure I've never used it. I can't think of anything I've ever done that would have required a hacksaw, but I know there was something once upon a time. I wonder if I made a good job of it...
