I started a small fire today (I was showing my son a one stick fire) and had used my BK14 for the wood processing. As we sat there playing with the various size pieces of wood in our small fire I took the empty sheath and blew in the end of it forcing a rather strong small direct stream of air out the drain hole in the bottom of the sheath. I probably looked like a duck with the sheath in my mouth but it worked extremely well to blow on the fire and keep my face a little farther away from the flames. Maybe this has already been talked about here but it was new to me!!
