Ode to a Wrench

I'd have been really stuck today if I hadn't had this baby with me. I went for an impromptu plein air adventure and grabbed some old tubes of paint in a hurry.  When I got on site I discovered the caps were stuck fast!  I would have had to pack up and go home if I hadn't been told to pack a wrench in my plein air bag.  Thanks, little buddy.
