Well, I carry a Schrade folding knife I have had since about 1981. It does show that I learned how to sharpen blades using it
A multi-tool and the most used tool is the pliers and they have saved my behind a few times. The Phillips screw driver and flat blades I have used only a few times.
A Swedish Steel fire starter.
3 extra mags with thumb loader.
1st Aid kit along with (2) pairs of nitrile gloves
Key lanyards which keep my house and car keys on me and not on the ground somewhere.
Sweat bands and paper towels.
At least one concealed pistol.
Many times if walking about, I carry a straight blade, double edge, full tang, knife in an easy and quick to access sheaf. Opposite side of the gun hand.
A 9v Palight flash light, a couple of pens or markers.
I carry one of those credit card tools, the knife is passable, but, it makes a great pry tool.
Extra length on the boot laces.
Two small bungie cord ties with the ball that you use for tarps. Those have come in very handy when I needed to start a flooded chainsaw. Plus, they can double as a tourniquet.
I usually wear two belts and a t-shirt and shirt. Extra belt carries the weight of the gun and can double as a tree strap in case I need to climb something or hold down strap with how I set it up.
I try to have a Bible in my truck (though with the mandela effects the KJV it is pretty useless now)
I try to be prepared.
