Does it make sense if a personal survival kit is housed in a cylindrical metal can that can float, be used as a cup and yet contain all the most simple, necessary and yet proven stuff for a potential survival situation? All Ive seen are those square or rectangular shaped PSKs!<br>If I were to make and sell the type of machetes that we used in our jungle survival and cross country jungle raids.... would it be easy to get into the US and what kind of " blade standards " are we talking about? Over here, our blades are made from the springs of cars and trucks that were involved in accidents and time and time again, it can cut through the tickest bamboos as well as hardwood, too. The trick is that one must constantly sharpened it and use it in the jungles!<br>Would appreciate your feedbacks on both these matters.
