Long ago a friend of mine, studying magic, came to me and asked to make him some lock picks. He was spending huge amounts of money on books just to learn the basics. Lucky for you, with the aide of Instructables, and your diligent time, you can learn this skill.
Some of this information is repetitious, but there is an endless way of doing things and just as many ways to get materials to do so. This guide is meant to give you a foothold on a very large subject and not spend as much doing it. Please understand some of the comments, and links, are just as educational as the instructable themselves.
