I hunt many things in many places.
I have a leatherman-like tool permanently attached within the game pouch of my vest.
If the hunt is more remote, I take my ELB.
If a jaunt in the area, my most welcome piece of kit is just a bottle of water. It is just very amazing how simple and delicious a drink of water can be in the field.

I usually have a thermos of coffee in the truck as well, but that is for between stops.

For those that maintain a slide-in set of drawers, I recommend a Jet boil, and some coffee/boullion crystals.

Out there doing it best I can.
