More selfmade weapons: selfmade knife

Here we go again with even more weapon technology from "postapokalyptica". These guys teach you how to make your own knife!

I started with some leaf spring from a 57 Dodge half ton pick-up. Leaf spring from US made cars and light trucks from the 1950s and 60s are made of a high carbon steel alloy called 5160. This alloy is an excellent choice for almost any kind of knifemaking. 5160 has 0.56 - 0.64 carbon, 0.75 - 1.00 manganese, 0.15 - 0.35 silicon, 0.70 - 0.90 chromium. It has great edge holding abilities and can withstand prying sideways better than most high carbon steels. I heat the steel in the forge to a non-magnetic state and hot cut a chunk about 7 inches long and about 2 inches wide...

Make sure to learn how to make your own! This may be the advantage you'll need one day to survive ;-)
