Here is my opinion. Tom Brown Tracker. I say this for MANY reasons. First I'm going to go with the negative factors (that I'm aware of in it's design). It's a LOT heavier than than the Bushman, the saw on the top of the knife is pointless and only adds weakness to the overall knife, it doesn't 'excel' at ANY thing, it's pricey, and it's HEAVY! With that said however, it does a has a lot of potential. First, you can use it as a hatchet. It will do GREAT at chopping things because of it's hatchet like design. Batoning wood, chopping down green/dead wood for whatever you need it for, or cutting up and skinning a large animal. Do you want to chop through the rib cage of a deer with that Bushman? Can you do those same things with the Bushman without jeopardizing it's edge or overall blade? Seriously, do you think it'd do 'good' with cutting down 5" thick oak or batoning wood with a diameter of 12" or greater? Probably not, the blade and grind (to me) is far too thin. On top of that, The Tracker will be able to skin, slice, whittle 'okay.' No, it's not going to be 'GREAT' at those things but it WILL do them. The Bushman will also do all of these things but at what cost the edge or the well being of the overall knife?
I too have a Tops 'Survival' knife and will be soon getting rid of that problem. As far as weight/usability goes it's more a liability than a 'help.' I'm getting a bushcrafter's knife that has a 5" blade 1/8" thick that will serve ALL my wood crafting needs in a survival situation. I've also got a small skinning knife and a multi tool. These 3 will still be lighter than my 'survival' knife and serve FAR greater functions.
