We all have old keys laying around the house and if you don’t they only cost around 2 bucks. The key to survival (no pun intended) is to adapt and to re-use what you already have around you. For example, an old milk jug can be up-cycled into a mini green house for a plant or cut into a food dispensing scoop.
The same can be said about a humble key. Did you know that you can hack a key into a very useful and probably lifesaving tool that you can keep with your regular keys? Make a few and give them your friends and family.
Some examples of what you can do with this little tool are: 1. drill (better efficiency than Phillips screwdriver) 2. saw (wood) 3. bottle opener (beer) 4. rope cutter (nylon, cotton ….) 5. screwdriver. Check out how to make this simple tool in the link below.
