Oh goody goody. Another one. Way to go Roxann and LilRose

Yup, I knew my other post was in the wrong place, but just couldn't restrain myself from sharing. I mean, it was important. Have you ever imagined a life without a potato masher? Potato mashers are very important. As are manual can openers. And a stovetop or camping coffee pot that will last and not have it's handle melt or fall off.
A potato masher that you can wave around in the air threatening others while sipping a cup of hot coffee makes any situation more tolerable.
A hand egg beater is nice too. Would make mixing that cake by hand a whole lot easier.
A flour sifter would be priceless if you need to sift course grains, or things get so bad that bugs are hungry and decide to dine on your wheat. Ugh. There will be those who say the protein would be good for you, and they have a valid point, but unless it becomes REAL bad, I think I'd prefer not to have bugs. But if I did, I'd sure like a way to filter them out.
One of those little manual food grinders would be real nice too, if you have little ones, elderly, or sick. Jars of baby food could become a thing of the past, and it would be good to have a way of making their food palatable and mushy enough to eat. Elegant way of putting it, isn't it?
A Victorio strainer is also wonderful. I use mine more than a food processor, and it's manual. It's a real work horse. Depending on the screen you use, you can put fruit in one end and skins, seeds, etc. come out one end and puree or pulp come out the other. Makes salsa extra simple, and any soft food, cooked potatoes, squash, beans, could be made fine enough for a baby.
Jars and lids, jars and lids, and more jars and lids. You wouldn't want to be in a position of stumbling on a great stand of wild veggies, or have a deer drop dead of a heart attack in front of you, and have no way of preserving them.
Washable cotton, or flour sack material. Endless uses. Straining jellies, fruit wines,
protecting food to be dried in the sun, dishcloths, drying cloths, hand wipes, aprons, wrapping bread, tying herbs or tea to simmer in water, head cover, bee swatter, produce carrier, wet to cool around neck, or, in case of water shortage, to be dragged across the early morning grass to soak up the dew, and squeezed out for water. You can't have too many of them.
Cast iron. Seasoned before you need to use it. The copper bottomed stainless steel are wonderful now, but become quite useless over a wood stove or open fire.
Hand grinder for grain, coffee, herbs, etc.
Bars of Fels Naptha soap, washing soda, and borax, to make laundry, dish, and body soap. Measure 3 pints of water into a cooking pot. Add 1/3 bar grated Fels
Naptha laundry soap. Cook over medium heat until dissolved. Stir in:
½ cup Washing soda, ½ cup Borax. Stir until it thickens like honey.
Remove from heat. Pour 1 quart of hot water into a two gallon
bucket, stirring in the thickened soap mix. Stir and mix until well
blended. Cover and set aside for 24 hours. It will gel up.
Use ½ cup for each load.
Add some essential oils and you can be elegantly clean. Citrus fragrances repel critters like mosquitoes. It's inexpensive to make and does a decent job.
A few durable plastic or rubber bins to wash dishes, clothes, a child, or dog. If you're picky you could have separate ones for each job, but it might deter those hanging out for a meal if you put the dog in, scrubbed him good, and then put the dishes in.
Spray bottles to use for disinfectants for food, counters, etc. Plenty of bleach, grapefruit seed extract, vinegar, etc.
Oops, splicer says I better hurry up or everyone will have posted all my ideas. But, never fear, I'll think of more.

Sure do love these threads.
