Here is a wonderfully useful tool for automotive Locksmiths who need a quick way to work on Ford 8-Station locks.   Made from Peterson's famous government stainless steel, these 'tryout' keys will last a lifetime.  Keep in mind that it does require some practice to make the most of any jiggler set, as they work in a way quite different from an actual working key.  With some patience and practice, you will soon think of this set as indispensable.
