Bushcraft generally refers to wilderness survival skills and was initially used to describe the survival skills needed in the Australian bush country or outback. The isolated outback territory meant whatever you took with you when choosing to go on "walkabout" was pretty much all you had. You lived off what you had until you returned home or reached your destination.
Buschcraft has now become pretty much synonymous with wilderness survival regardless of your location. And whether by choice or circumstance, if you rely on only your supplies and skills to live off the land for an extended amount of time, a good bushcraft knife becomes an essential tool.
You can't just bring along any old knife and expect it to hold up to the repetitive, rugged tasks you need to perform to survive in the wild. A bushcraft knife also called a wilderness knife, is a popular style knife because it can repeatedly perform multiple tasks like dressing game, cutting tree limbs, rope, and fishing line or even some carving.
