EMT Shears: Not only will they come in handy to cut bandages and cloth, but they can be taken apart for more heavy-duty cutting.
Rubber Boots: These are a must. And get the heavy duty insulated kind so your feet stay warm and dry. Because frostbite tends to suck.
Rope: It is the item that pops up on most of these survival lists because it serves so many different purposes. Bring along at least 50 feet of the heavy duty variety.
