A survival knife with a fire starter is a recommended combination by Modern Survival Blog for general applicable carry. Having both a knife and a fire starter will serve as excellent bushcrafting tools. Bonus: It will also help assure your survival. I personally like the knife sheath that includes a holder for a fire starter such as a firesteel / ferro (ferrocerium) rod. It’s just a perfect combination. There’s nothing wrong with separately carrying a fire starter but this keeps it all in one place (the knife spine as a striker and the fire starter rod tucked in the sheath).
