Challenge

It's the last day of the March challenge, so I will set you a challenge: what is this?

The challenge today recognsises that we all have "stuff" and asked us to show this in a photograph. Unfortunately, I couldn't find my stuff, because it was hidden under other stuff. So instead I photographed this. I can offer a clue: I am doing some DIY work on the house at the moment and this is a tool from my garage which I might be using.

If you can't guess, I'll reveal all in a couple of days.

EDIT: someone off line (not a Blipfoto regular) recognised this as detail of a mitre saw. You could probably only guess if you had one yourself.
