Seriously, this looks like something you would carry in the jungle!! Definitely a unique tool in that you do much of your cutting and clearing simply by hooking and pulling - the tool does the cutting. Doesn't come all that sharp - so some would want to hone the blade a bit. It does come in one of those stupid plastic packages that is such a pain to open. Comes with a handy cover so you are protected against accidental damage. I didn't try to use this as an edger, but to me it didn't seem like it would do as well at that as simply in clearing, weeding, and pruning.
They do make it in larger sizes which would extend your reach and increase your leverage, but for some jobs, the smaller size would work better.
