I have ready next to my B.O.B. is a Ninja sword , razor sharp , my reason is if i am on the run and run out of ammo . What is the best weapon i can carry , it must have good tactical use , I can cut off a man's arm or head... no joking... If i need fire wood i can get all i can ever use by jumping up down on it with boots, and to be tactical walk around heavy bush.. and not leave a trail... I do carry a very good and sharp K-bar, and a very good folder knife in pocket... If we lost this world as we know it at some point the ammo runs out... think Middle Ages! so the Ax stays home...
