This post may fall flat on its face, but after buying a 90 degree drill adapter for a job on the car , I though I would hardly use it again. How wrong I was it's been used plenty off times on the car and even helping me put cornicing on a wardrobe, due to a low ceiling. So this made me think what other outside the box tools could I not live without? That I pondered about buying for fear off not really using in the first place. My dremel, digital caliper and ickle 50mm air orbital sander all come to mind. What's yours.
