Some people carry both, but most choose one or the other. Multi-tools are nice for everyday utility like opening a bottle or fixing a screw on your sunglasses. There are tons of great options from popular brands like Leatherman and Gerber. But as in most things, the 80-20 rule applies here, and you’ll find that you won’t use most of the features in the extra-gadgety options and should avoid the unnecessary weight.
In the US, long guns are subject to fewer restrictions than handguns, chiefly because of their negligible role in street crime; that said, "assault weapons" - i.e., semi-automatic rifles with scary-looking cosmetic features, such as barrel shrouds or forward grips - have been a subject of recurring moral panics and various state- or municipality-level restrictions and bans.
There are other ways to absorb the anxieties of our time. “If I had a billion dollars, I wouldn’t buy a bunker,” Elli Kaplan, the C.E.O. of the digital health startup Neurotrack, told me. “I would reinvest in civil society and civil innovation. My view is you figure out even smarter ways to make sure that something terrible doesn’t happen.” Kaplan, who worked in the White House under Bill Clinton, was appalled by Trump’s victory, but said that it galvanized her in a different way: “Even in my deepest fear, I say, ‘Our union is stronger than this.’ ”
Rope, look at AmSteel-Blue (it’s the diameter of paracord but much, much stronger 8.5 mm is rated at 1600 lbs) it’s light, easily packed and available in larger, stronger sizes too (maybe Gaye can link it on Amazon?).

Survival kits, in a variety of sizes, contain supplies and tools to provide a survivor with basic shelter against the elements, help him or her to keep warm, meet basic health and first aid needs, provide food and water, signal to rescuers, and assist in finding the way back to help. Supplies in a survival kit normally contain a knife (often a Swiss army knife or a multi-tool), matches, tinder, first aid kit, bandana, fish hooks, sewing kit, and a flashlight.
