Jason, I suspect the plastic screwdrivers referenced in the Pina books are inexpensive TV adjustment tools sold at places like Radio Shack (or they used to be). These are actually plastic shafts with a small metal piece molded into the plastic to do the actual adjustment. These work, but tend to wear out quickly as lightweight plastic is not ideal for longterm use. The better choice is to use either beryllium or ceramic tools (the key is non-magnetic and non-sparking). There are some health concerns with using beryllium (though I suspect it is like asbestos in that you generally need long term exposure to have any health effects). You can get ceramic tools at a variety of sources... I use Techni-Tool for most of my speciality tool purchases. Be careful when adjusting a ferrite though... They are quite fragile and if they crack they are useless.
