The list author says: "This list is an expansion of the previous, "Basics and Storage". Obviously, the more essential items are left out here, but these items should be more useful to those with more experience in camping or other outdoor-based survival."
"The KA-BAR is one of the finer knives out there; the serrated portion may be a bit difficult to sharpen in a survival situation, but the quality of the steel should buy you some time to get acquainted with your sharpener/whetstone before that happens."
"Good for both straight and serrated edges; it'll be much easier to sharpen straight blades than serrated ones, though. Make sure to practice and become proficient with it before a survival situation arises."
"Occasionally, you may find yourself in a situation where you cannot use the Firesteel or have run out of pocket tinder from the compact survival kit; magnesium burns very hot and should be able to ignite even in wet conditions."
"A mobile manual saw, for extended survival situations. The teeth may or may not be sharpen-able with the Smith tool, so use sparingly; once it goes dull, experiment to find out what method could work in the field."
"Instead of going for the rubber trench boots, use these current-gen duty boots; they're based on the design of the much more comfortable hiking boots with much more endurance. You should learn how to make your own shoes from animal skins before these begin to wear out."
"Portable shelter for one. It doesn't weigh too much, but will provide ample protection for most conditions. Waterproof it yourself to make sure it'll stand up to rain; when using this in more hostile conditions, try to locate it under some kind of overhead structure at all costs to reduce wear on it."
"This looks exactly like the kind of thing you'd expect to see a survivalist carrying, and it might as well be; it's extremely rugged, well-made, and has plenty of accessorizing potential, if you decide to do so later on."
"To expand your carrying capacity or to be used as a standalone "scout" module for hunting. It can also be used for its original purpose (medical kit) or any number of things; it's a large enough pack/pouch that it might even be usable for several purposes at once."
"The goal with these sunglasses is not to look cool; general sun exposure to the eyes can easily wear down your vision, and snow blindness can be deadly if you are alone once the damage presents symptoms."
"This flashlight uses much heavier "C" batteries, but lasts for more than 100 hours with all six LEDs online and has a 3-LED and Xenon mode, along with having the same waterproof/regulated qualities of the subcompact Microstream."
"The longest-lasting flashlight you'll ever bother to find. This one gets over 336 hours on a single set of C batteries; while C batteries are bulky, this flashlight is well worth the weight. Its beam is incredibly bright as well, several times more than their other products such as the Microstream."
"If you aren't willing to put together your own kit, this one is about the closest you can get to one that covers as many bases as possible out of the box. For a long-term kit, you'll need to splice together your own kit."
"Expensive, but worth it for a long-term scenario. If you're okay with surviving at the cost of temporary menu fatigue, buy an equivalent amount of Essentials from the previous list; they come out to around the same cost, but the Essentials come with a supply of water and a survival blanket as well."
"If you survive but find yourself alone, keeping a running log of events could be the one thing that keeps you sane. The paper is acid-free, so the notes should last for decades to come (contemplating past experiences can also help you cope with a survival situation)."
"If you can afford the space, these binoculars should suit the job well; it'd be preferred to not use a rifle-scope, because the optics or mounting components could get damaged, and a scope doesn't exactly make it possible to use the iron sights in a close-up and personal situation while hunting."
"The epitome of a self-contained hunting air rifle; .22 caliber with enough power for rabbits, does not require anything but air, has its own pump built into the mechanism, bolt-action (ensures loading), and only requires PellGunOil for most maintenance. Use with Crosman Premier Domed 14.3 gr. If you live at high elevation, buy a Chrono and figure out how many more pumps you need."
"You can use it to make your own soap, provided that you know how to react fats with it; isolate it safely within a container. Alternatively, you can research a method to extract potassium hydroxide from tree/bracken ashes."
