AXE verses Machete for SHTF

Lets get serious....most people when they talk about bugging out it's because they think the world will figure out safety within 72 hours and you can return home. However what if the PUNDITS are wrong? What if starvation is your enemy? What if your life is depending upon what TOOLS you bring with you during this FIRE DRILL? I think you are going to find that Size and Weight constraints are stupid. CALORIE burn is what will matter.
