I saw a little mini-hacksaw at Countycomm, so that is what inspired my idea. How useful would it be to keep just a hacksaw blade in your bug out bag? It would weigh hardly nothing, take up no room (because its flat), and could possibly get you out of bind where you need to cut a piece of metal. A handle could be fashioned later out of a stick and 550 cord and hacksaw blades are cheap. What do you think?
