Bushcraft is a term, I think British origin, used to characterize tools, methods and activities you would do on a primitive camping or survival outing. A bushcraft knife is a knife designed to prepare wood for a fire, make feather sticks, strike good sparks, make tent pegs, etc. If you build a shelter with items found in the woods that is Bushcraft. If you make a primitive deadfall trap that is Bushcraft.... and so on.
