The wise outdoorsman always has a multitool with his survival gear just in case. They’re light, affordable, and in the case of the Leatherman OHT they’ll put the venerable Swiss Army Knife to shame. The OHT features needlenose pliers, spring action wire cutters, a high carbon blade, a serrated edge, a can opener, Phillips screwdriver, bottle opener and myriad other attachments.
In the previous decade, preparedness consultant, survival bookseller, and California-based author Don Stephens popularized the term retreater to describe those in the movement, referring to preparations to leave cities for remote havens or survival retreats should society break down. In 1976, before moving to the Inland Northwest, he and his wife authored and published The Survivor's Primer & Up-dated Retreater's Bibliography.
I.N.C.H. pack: I'm Never Coming Home pack. (It is another name for a Bug Out Bag. often used by those trying to show that they are experts in the preparedness field.) A pack containing everything needed to walk out into the woods and never return to society. It is a heavy pack loaded with the gear needed to accomplish any wilderness task, from building shelter to gaining food, designed to allow someone to survive indefinitely in the woods. This requires skills as well as proper selection of equipment, as one can only carry so much. For example, instead of carrying food, one carries seeds, steel traps, a longbow, reel spinners and other fishing gear.
The Modern Lifestyle Prepper is another one to avoid. It’s not just a game of stock up enough to maintain creature comforts until normalcy is restored. A genuine situation will require the skills and abilities survive with what is available. Can you build a shelter, how long will it take, can you make fire, do you have basic medical knowledge, can you actually trap an animal, can you walk into the woods right now and get dinner?
For personnel who are flying over large bodies of water, in additional to wearing a survival suit over cold water, a survival kit may have additional items such as a small self inflating raft to get the aircrewman out of cold or predator infested waters, flotation vests, sea anchor, fishing nets, fishing equipment, fluorescent sea marking dye, pyrotechnical signals, a survival radio and/or radio-beacon, formerly a distress marker light replaced by a flashing strobe, formerly a seawater still or chemical desalinator kit now replaced by a hand pumped reverse osmosis desalinator (MROD) for desalinating seawater, a raft repair kit, a paddle, a bailer and sponge, sunscreen, medical equipment, a whistle, a compass, and a sun shade hat.
And, of course, people aren't going to stop wanting to get drunk just because they can't pop over to the corner bodega for a six pack whenever the urge strikes. Portability and long shelf-life make liquor of all types a valuable trade good -- people will kill to get a taste of the delicious bottom-shelf leftovers from your local dive bar when their only other option is the equivalent of prison wine.
This group stresses being able to stay alive for indefinite periods in life-threatening wilderness scenarios, including plane crashes, shipwrecks, and being lost in the woods. Concerns are: thirst, hunger, climate, terrain, health, stress, and fear. The rule of 3 is often emphasized as common practice for wilderness survival. The rule states that a human can survive: 3 minutes without air, 3 hours without shelter, 3 days without water, 3 weeks without food. 
Radio transceiver, standard VHF marine when operating near inland shore, 121.5 MHz AM VHF guard channel capable aircraft band transceiver to contact rescuers and high overflying commercial and military aircraft visible by contrails, an optional amateur radio if a licensed radio amateur, (see Ham Radio) or an AM/FM/Weather/Shortwave radio receiver to receive precise time for celestial navigation as well as weather information
Cigarettes will also be hugely useful for starting fires and saving coals (as any fan of post-apocalyptic literature knows, this is of great importance). The filters can be used to clean water, although you'll need the patience of Stephen Baldwin to pull it off. If you do manage to live for longer than a few weeks without plumbing and Internet, you'll be able to protect your budding prepper garden by soaking cigarette butts in water and spraying the resulting chemical-laden tobacco juice on your produce. This is a technique already in use by people too impatient to wait for the apocalypse, though it is ironic and entertaining that they consider using cigarette-butt sludge a "natural" way to ward off pests.
The most dangerous people in a survival situation is the gang of outlaws who only want to take what they need and don’t care about what happens to the owner(s). The hardest to know what to do with, and for, is the individual (person or family) who has done nothing to prepare for emergencies or disaster. It’s hard to want to help someone who does not, and will not, help themselves. But it’s endemic to our society – it’s all about big brother taking care of you, or “the government” being your friend. It’s about entitlement. It’s about not caring about other people, only yourself/family. They are the 2 true dangers to preppers.
These individuals study End Times prophecy and believe that one of various scenarios might occur in their lifetime. While some Christians (and even people of other religions) believe that the Rapture will follow a period of Tribulation, others believe that the Rapture is imminent and will precede the Tribulation ("Pre-Trib Rapture"). There is a wide range of beliefs and attitudes in this group. They run the gamut from pacifist to armed camp, and from having no food stockpiles (leaving their sustenance up to God's providence) to storing decades' worth of food.
We get that creature comforts will be ever more important as the things that used to make us happy slowly break and crumble around us. But do you really want to put a ton of effort into opening a bakery when everything is going to shit? And we hate to be the bearers of bad news, but no amount of odor elimination is going to stop the uncivilized world from smelling really, really bad.
Each type you listed (save a couple) will have its uses in a community (group if you will), generally having a small trusted group with each having several skills in the various fields (prepper, homesteader, and survivalist) I believe would be an effective team, though as each group works together would it not be best to ensure that each has overlapping skills in case of injury, death, or other reasoning they can not fulfill their duties?
Earthquakes, tornadoes, and hurricanes can cause you to leave your home or even be trapped there. Roads could be blocked due to fallen trees, power lines, or even damaged earth from the natural disaster. Rescue crews can not be in all places at once. You may have to wait it out for quite a while before its over. You won't be able to go to the store or to the corner market.
