A lot of what we discuss here at Survival Today involves preparation — all the things that we should do before any disaster happens. We should also learn as much as we can about what to do in case the disaster situation is prolonged.
One useful bit of knowledge is how to build your own tools. The folks at HomeMadeTools.net have done a fantastic job of compiling over 4000 how-to guides.
You can learn to make handheld tools like hammers and drills, to larger equipment like lathes and table saws.
