Great design to keep in the bushplane or for any last ditch scenario, if you know how to use it. It is a very specialized tool, a bushcraft kinda thing. I guess if you had only one tool...
If you are going to war, you might find it handy. If you just want a tool for civy use, get a knife
I would never carry one. I prefer a smaller 3-4" fixed blade. Between that and a pocket chainsaw I can do anything a Tracker can do, and a lot it can't.
In my opinion Trackers are kind of a 'Rambo' thing.
I wouldn't put up with the size and weight of one, therefore, I wouldn't have it when I needed it!
Rambo survival knives, Trackers, Woodsmans Pals, seen 'em come, seen 'em go! I've even owned a few! I always come back to a good smaller knife.....
