Friday Favourites - The Tool Edition

For lack of a better term, I've labeled this week's edition "TOOLS".  If it makes your life easier, saves you time, and fills a need, what else do you call it?

This is my current favourite - and yes, it's a dinner bell.  When you've got four boys making noise, nothing beats the clang of this baby.  I found it at a little shop in Rosebud, Alberta, and my lovely sister bought it for me :)

"Come and get it!!!!!"

What's your favourite tool?
