Hi BigCountry73,
Welcome to Bladeforums. Its good to see another Adirondack outdoorsman. I spend quite a bit of time around Essex and Hamilton County. Its a great place, as long as the black flies dont eat you alive.
Ive tried a few different large knives in the Adirondacks, but they never seemed like a very good fit. They were too large and heavy to live with during the hot and humid weather, or too small to be of much use. Ive since taken to using a 3-piece approach, which has worked out very well. The first piece is a good small axe or hatchet. Youll probably hear a resounding recommendation for Gransfors Bruks (
http://www.gransfors.com/ ) if you want a good brand name. Id go for a hatchet if you plan on doing a lot of traveling, or an axe if youll be staying in one place.
The second piece is a Marbles fixed blade (

These are knives designed for hard use in the northern part of the US. Id get a Marbles Woodcraft to match with an axe, or a Fieldcraft to match with a hatchet. Marbles makes excellent hunting knives, which happen to also excel at woodcraft. Its a win/win choice. The only downside is that their sheaths arent all that hot. I usually end up making my own.
The third piece is a venerable Victorinox (
http://www.victorinox.com/ ) Swiss Army Knife. Id personally do something like a Camper. It has two blades and an excellent saw. If you also need scissors, the Huntsman is a great choice. If you do a lot of fishing, something like a Leatherman Wave or Juice might be more appropriate. Youll get a set of pliers that way, and still have a saw. The tools wont be as easy to use and comfortable as a SAK, but youll have everything you need.
When you have a couple of different sized blades, a good saw and a chopper, youre good for just about anything in the Adirondacks. You have everything you need for cleaning game and building a camp from scratch. All of the brands Ive mentioned are available from Smoky Mountain Knife Works (
