Build and Repair, ...got any ideas? Options

Survival. It's etched in all of us to survive.

With this comes the idea of the survivalist character, the one with good Willpower and the skills Armorer, Industrial Mechanic, Survival (obviously) and the relevant knowledge skills that will allow said character to find food and water without contracting diseases or ingesting poisons.

So what I'm asking of the community is ideas for things that a person could/ should create if they were dropped in the middle of nowhere, be it forest or the Barrens. Write down your ideas along with threshold number and interval time to create said item, and if it's complex or just odd what might happen if a glitch occurs. :D
