I have a bit of modern technology that I can make available to the modern day "prepper" as well. There is a new tool for making fire in an emergency situation but it is also a fuel source. I am planning on selling them in 10 packs individually packed @ $20 per 10 pack. "What is 2 bucks when you need fire?"
I have the opportunity to out do the trend of everyone buying "wimpy parachute cord" for their survival kits. I have several spools of genuine Air Force surplus "flight line" that I can sell at reasonable per ft rates.
I also have a line on genuine, not the standard US consumer model, original METRIC Swiss Army knives.
