1. Pencil Sharpener
When something happens and you have to do your best to survive in nature, you need to manage your resources carefully. You donโt want to shorten the life of your gear by using it when you donโt need to.
What we mean by this is that you can sometimes perform some tasks with the help of equipment you can do without, rather than using essential equipment and destroying it faster. For example, if you have a knife, you want to keep it in the best shape possible for the longest time. If you want to cut branches to make a fire, you can snap them between two trees instead of cutting them with a blade.
In the same fashion, if you need tinder to start a fire, a simple pencil sharpener can do magic. This item is perfect for this task; it takes almost no space (you can keep it in your pocket), and you will not dull the blade of your good knife.
