Does anyone use rope saws in their kits? What brand do you guys carry that is durable and isn't some wimpy chain that's going to get stuck or break? Sometimes I feel bad about chopping down a whole tree just to cook and stay warm when there aren't any small trees or fallen ones. I figure the next best step would be to just cut off a branch instead of a whole tree. What rope saw do you guys recommend that is tough and durable that I can tie paracord to each end and pull back and forth?
