The Tracker is not a good knife. Tom Brown is an excellent wilderness survival teacher, but the knife that he made, The Tracker, is just a hunk of useless metal. However, it's a really high-quality made item; it's just the design that sucks. I've owned one and it is crap. Nothing about it is good. It is like chopping down a tree with a shovel, carving with a table knife and sawing with a wiresaw. It does everything, just not very good.
Regarding ESEE, I must say that I have more use of my fully convex-modified Izula and a regular Mora, than I have with my RC6. It has an excellent build quality, but the design isn't top notch. The edge contact is in front of the grip line, making it less controllable for fine cuts, there's a finger choil instead of a fine carving area, which could be OK, it's just that when you're carving for any longer than a few minutes, then it becomes uncomfortable to do so, because the spine of the blade (with f&%#ing jimping!)is digging into your palm-area between your index finger and thumb.
The handle area is really heavy compared to the blade, so as the blade wears down, the weight of the knife will become more and more focused in the palm area, which isn't optimal for chopping. The pendulum-effect is not in use.
Like I was on about with The Tracker, the build quality and finish are great, it's just the design that isn't as well executed.
Great quality stuff, just less than perfect designs. Putting on my flamesuit...
