Inner Tube also make great Hatchet or Axe Sheaths. Just staple a small piece of wood to the inside and wrap it around the Axe or put an extra wrap in the inner tube. Easy to get on and off. Simpler to make than a leather one and definitely a recycling project. I use car/truck inner tubes and pieces of hockey sticks and if i want a nice one I hollow out a bit of the wood so the Axe/Hatchet rest nicely in the hollow. It also means you have an excellent source of the worlds smokiest tinder.
