A machete is hard to swing in a dense jungle. A short hand saw like the Stanley Short Cut works better in tight quarters. BUT, EVEN BETTER, is a cordless reciprocating saw. A Sawzall type thing, battery powered. I pinned the deadman's safety switch on a Ryobi cordless saw (for easier 1-hand use) and really did a number on some bushes and 5-foot tall thorns and kudzu in my yard. Just grab a handful of vegetation with one hand, pull it tight, and saw it though in a second. It lets you reach out pretty far, too.
