As you've ordered the TGLB, further input is probably moot but it makes for fun discussion.
While I have my personal opinions on 'survival' vs. 'combat/field' vs. 'camp' vs. 'fighting' knives, overall I think the TGLB is a solid overall design--basically an INFI KaBar on steriods. I don't see myself wanting to get in a knife fight with some wild critter, but I know of a man in our area that not so long ago turned around to find he was being stalked by a very large cougar (or at least that was the account that was related). He basically point shot with is rifle from 'crap your pants distance.' Had be been in a wooded area and the cat could have gotten closer, or had he not turned around, the rifle might have been taken out of the equation and he might have had to resort to whatever he could still get to. Point being, while highly unlikely, never say never. So if that's a concern in your mind, and the double guards give you some comfort, I say go for it. If it works for you, I'm not gonna say no. As I say, the TGLB looks like a good overall knife, and there is some comfort to be had from positive guards.
Now as to survival knives, to me 'survival' means something has gone wrong and you've moved from recreation to 'uh oh' through chance, accident, nature, etc. We'd all be so lucky to have our Busse or other quality fixed blade with us, but in reality, as most of us don't really relish the thought the brown stinky stuff hitting the oscillating wind-generating unit, we'll probably have to make due with whatever we have with us at the time. That might be a little SAK or folder.
Combat/Field knives are those, in my mind, that are intended for hard use in field conditions. Opening crates, opening cans, and all those other chores where blades do things other than just cut because you can't carry all the nice convenient things with you all the time and the knife becomes a multi-tasker.
A 'camp' knife is along the lines of a field knife, but general related to tamer activities in controlled conditions. It'll be primarily regulated to cutting as originally intended. This is the realm of the nice, satin finished smaller/midsized knife that will cut some twine, make some tent stakes, slice open the food packages, etc.
The 'fighting' knife might be less utilitarian than the others...it has a dedicated purpose not related to general field/camp duties. This is going to be your daggers, tantos, etc.
There's obviously overlap and one can be pressed into the other role(s). Truth be told, I don't think there is one 'perfect' all around knife. But if I had to choose one fixed blade to walk into the woods with for an unknown excursion, it would be my CG NMSFNO in SpecOps sheath with fire steel, SAK folder, and whistle/compass gadget. There are very few chores in the woods I don't think it couldn't handle, and it isn't an unwieldy monster. The TankBuster would be a very, VERY close second. If it were a camping type outing under controlled conditions, a SFNOLE would be very tough to beat (tho my custom NWA is right there as well).
But I certainly wouldn't fill ill equipped with a TG at all in the woods.
Just my $.02 worth, YMMV.
