I do not really know who started the mantra of one is none, two is one rule of survival and preparedness planning, but it is a great notion to cling to. For instance, if you are hiking alone in the woods and you lose your compass, you are screwed. I know, some will say “but I use a GPS, those are almost impossible to lose”. Maybe so, but suppose the battery goes dead? Do you see my point? If you only have one of an essential item, and you lose it or it breaks, then what?
The same goes for any other tool or bit of supply you may need in your survival plan. I remember a couple of years ago I was opening a can for supper, and the can opener fell apart after a couple of cranks of the handle. I had another can opener in the drawer, and luck had nothing to do with it, so it was no big deal. However, if I had no backup tool in waiting, I would not have been able to simply grab the back up and finish preparing the meal.
I would have had to do without, compromise, or get primitive and open the can with a huge knife. That would have been a pity as the blade would have needed substantial attention after slicing through the metal can. One is none, two is one. It is a good rule to follow and should be a central consideration as you develop your preparedness and survival plans.
One drawback to this goal of having at least two of your essentials on hand is the added cost. You have to plan on double the cost of these essentials, thus doubling the size of your preparedness budget as it relates to these essential items. Is it really necessary that we have two or more of everything? Not really. There are times when we can get away with making concessions. We may be able to come up with alternative tools or devices to compensate for the loss of some of our needs.
One suggestion I can give here is to make sure that you keep these extra tools in a separate place. Have an extra box of additional tools, but keep it close enough that you can access it when the need arises. Unfortunately, far too many people utilize offsite storage for the excess baggage we consider as needs today. Personally, I consider offsite storage a waste of resources. The money that you spend on locker rental fees could be better used for buying the things you need to develop your preparations for the coming times.
The fees for these lockers can be pretty hefty, and in some cases may be enough to equal the cost of a good supply of long-term storage foods. A one hundred dollar a month rental fee equals 1200 dollars a year. How often have you seen food deals for several months worth of food for that price? Just this week, I received a flyer from a mail order house offering a six-month lunch and dinner supply for one at only $1,299.00. That is not a bad deal, and you could afford it if you can afford to pay that much for a storage locker full of household goods that you do not use.
If you do use this arrangement, perhaps you need to include this aspect of your life in your overall preparedness plan. Seriously consider what you are paying storage fees for, and decide whether it really makes sense. Granted, there will be instances where there is no other option, but for the most part, much of what we have stored in these lockers have little real survival value. If the crap hits the fan and you become forced to shelter in place, will this locker be of any benefit to you? If you have to pack up the bug out vehicle and get out of town, what happens to the stuff you have paid all that money for in storage?
I know some people who have a rental unit as their central bug out command post, with a vehicle inside it ready to roll at a moment’s notice. They keep the truck and trailer fully loaded with MRE’s and long term storage food, along with all the tools they will need to survive if they have to leave town in an emergency. This is a good plan, and, providing you can afford it, and the unit is accessible 24-7, go for it. but it takes a certain level of ability as well as acceptance of the facts to be able to comfortably commit to these sorts of resources.
Whatever you decide to do, make certain that you are comfortable with your choices, that can afford your choices, and that you have considered all aspects relating to that choice.
 $1,299.00 for food for one may sound like a lot of money, but the reality is that it works out to only $216.50 per person per month, for two meals a day. A little over three bucks a meal. When was the last time you had a nutritious meal for that kind of price? It costs an average of eight bucks for a burger, fries and a drink in most fast food places today.
