As in the title. This is a survey thread. Nearly everyone has a favourite tool, be it a kitchen knife, sewing attachment, or chain saw. What is yours?
Mine at this moment is a great little Ryobi hedge trimmer/grass cutter. It is a one-handed battery tool that I have been misusing to clear horribly overgrown weeds and vines from my property. It has really been a lifesaver. I don't know what I would have done without it.
My other favourites are the Ryobi electric drill, which I mainly use as a screwdriver, and the Stihl battery chain saw.
