Well I finally gave it a try.
Holy crap, it was so easy and just slices through anything up to an inch with ease. I can’t imagine any other tool to be anywhere near as effective for these brambles. Giant mass of bramble in the way? No problem. Give it a couple slices and use the machete to fling it aside. Specific 3/4″ branches? Even easier. Aim for each one and it just slices through like butter. I can alsoalso it to kinda toss aside the sticks. The one thing it’s not good for (at least on a first try) is stuff close to the ground. Gotta stomp that stuff and I still got some nettles, but nettles don’t bother me that much.
Also it really wasn’t tiring at all. I only used it for ~45 minutes, but it doesn’t take much muscle.
