The title of this thread was "help decide on multi functional knife". C'mon folks with Foxy Folly's, YCS etc. I would love to have opinions on these. I confess focusing on M43s and my friend reminds me that he hasn't heard enough dissent yet. Bring it on!
ASTK. (Amur Singh Thapa Knife) M43 on steroids. Like the M43 and CAK had a baby, minus the fullers. Doesn't dance as much as the 43, isn't as much of an anchor as the CAK.
WWII. Dedicated tool that can be used as a lopping weapon. Bullnose, no stabby stabby. Excellent drawknife. Didn't care for mine, felt awkward, passed it off to my Uncle and Cousin.
BDC (Burda Daily Carry) Don't have one. General purpose utility daily carry. Looks neat. Have to find reviews on it yourself/others chime in. Could be a good packblade.
Alternative. (If you can scare one up) Gunga Ram/Bonecutter in 15"-18" Dedicated choppers/processors. Bit heavy, doesn't dance. Fairly rare.
If you're going to be processing a lot of wood, get a folding saw. Either a KatanaBoy (folding chainsaw) for large jobs, or a Gomboy for smaller ones. If you're looking for a dedicated backpacking combo, I'd go with the BAS + Gomboy. Combined, they'll weigh less than an M43/ASTK, and you'll expend less energy using them. I should have specified that Wildmike used the M43 in CONJUNCTION with a couple other tools, including a saw. Most likely as a drawknife to save his smaller fixed/folder, I can't recall which it was. Kuks are cool, but they're not superpower invoking.

If I only had to pick one (tearing my nails out to choose) it'd probably be the BAS. Because I'd be carrying a dedicated saw with me. Still be lighter than carrying an M43/ASTK, and I'd expend less energy using them.
So that's my recommendation if you're looking for a bushcrafty/woodsy set. Get a BAS and a folding saw. Don't be scared of the dual handle ones, they're actually pretty neat.
BAS was one of the last firsties (first of a model) I got, and I wish it had been the second. My personal favorites now are tied up. First, BAS and Gunga Ram Special, Second, M43 and Samsher. At third, the ASTK.
Final non-khuk alternatives are the Talwar and Ang Khola Bowie. Both awesome. Talwar for LW, AKB for medium. Saw for heavy.
