What tool do you find most useful on the farm for general use (besides tractor)?

As soon as I put on a pair of pants I check to make sure I have my jack knife and a lighter. I don't smoke but I use it to light burn barrel, house stove torches and to melt the end of a rope if it's cut. Jack knife for everything from cutting string and bags to filling in for a screwdriver in a pinch. Recently I bought a small tool pouch that hooks to belt and modified it to carry cell phone and a pair of safety glasses so that I'll always have them handy. I believe dewalt makes an actual phone pouch that might do the same thing.
