I was wondering what are the knives of choice for you Quetico veterans.  I've carried a number of different options on my trips into the Park. (8 different 10 day trips over the past 25 years... yes, I'm a rookie next to this board's members.)

The past few times I've carried a large Randal Model 14 on my belt along with an old Leatherman.

I know it's a bit large, but I'm accustomed to using it and I've had it's size come in helpful.  While not ideal for every task, I've been able to use it for everything from chopping branches to filleting a lake trout.  I carry it on my belt because that way I'll have some effective tool on me if everything goes wrong and I'm stranded with just what I'm wearing.  (I do carry a small survival kit on me but that's a separate issue.)  

So other than the obligatory fillet knife we all bring, what are other folks knives of choice?

the usual fillet knife, a leatherman, and one of those little eating knifes that come with the spoon and fork that all clamp together.

have you ever had trouble crossing into canada with that knife? i would have to assume that most of the guys here on quietjourney dont have the same issues my group have with age (we are all between 20-24 now, but we started as 18 year olds and generally have a younger guy with us). weve been the victims of some really intense searches, ridiculous things even, so we keep it very simple. its to the point where we disclose that we have fillet knives when the ask for 'weapons' because of how weve been treated in the past. for that reason i tend to advise the guys to bring a fillet knife and a small pocket knife just so we dont have issues.

generally, if you cant do it with a fillet knife, pocket knife, and your hatchet, its not worth doing. if you have a hatchet/little bowsaw for wood, fillet knife for fishing, and a pocket knife for cutting rope/line/whittling, i cant really imagine anything else youd need to do

Folding Fillet Knife, Kershaw flipping folder on the belt lanyard, and the friend made hunting knife around the neck. I suppose anything could be a weapon if used properly

Trouble with a belt knife is that it isn't comfortable to carry a pack if the knife is on your belt - so I don't bring one.  A fillet knife, and a pocket knife work for me on solo trips (and a small folding saw) - for tandem trips, I add my machete, usefull for filleting those pollyhumpers that seem to crop up in threads quite often, but more useful for clearing portage trails.

DH Russell is my main blade.  Full tang.  Perfect for whatever from cleaning fish to batoning wood.  It also spreads peanut butter nicely.

Additionally I have a couple multi-tool type dealios.

A belt knife needn't be on your waist.  Mine is on a lanyard and is either attached to my little kit bag or around my neck.  Same lanyard has a whistle and I don't tromp without it.

A full tang belt knife is a must. 
Swiss Army knives, once the standard, haven't kept up with modern multi-tools imo.
