True independence means making your own tools. Luckily, Popular Science columnist Chris Hackett knows how to do just that.

In the latest episode of the Rebuild video series, he demonstrates how to make a chisel: sand a worn-out screwdriver into the proper shape, heat-treat it with a blowtorch, draw the temper, sand the hardened metal into a wicked blade, strop it, and your DIY chisel is ready for use. Easy, right? Well, maybe not—but it's all in a day's work for Hackett.
