If you’re ordeal is an extended one you can lash the Ultimate Pro Knife to a small branch to create a spear for catching fish or small mammals. The pommel at the butt end can be used to hammer tent stakes and that little thing hanging from the lanyard cord is a powerful emergency whistle that can take over emergency signaling duties from the tactical flashlight or your long range walkie talkies when the sun comes up. A top-notch knife like this is essential survival gear.
While survivalists accept the long-term viability of Western civilization, they learn principles and techniques needed for surviving life-threatening situations that can occur at any time and place. They prepare for such calamities that could result in physical harm or requiring immediate attention or defense from threats. These disasters could be biotic or abiotic. Survivalists combat disasters by attempting to prevent and mitigate damage caused by these factors.
To me, the best option is to store emergency food. How much? If you have none, store enough for a few days. If you have enough for a few days, get enough for a week. How much you store depends on what time frame you think you're at risk for having to be completely independent. The early settlers of the southwest liked to store enough food for a whole year and still do to this day!
