The analog CD extraction device is probably the most common tool created from a paper clip (see figure 1's red circle). Most don't realize that when they take the time to make an analog CD extraction device they have also made a make-shift ATX power switch (see figure 1's blue circle). This is a brief description of some useful analog CD extraction device's and other paper clip tools.
figure 1: analog CD extraction device w/ make-shift ATX power switchOver the years I've created some interesting and some not so interesting variations of the analog CD extraction device. As one can see in figure 2 this is the "Travel analog CD extraction device w/o the make-shift ATX power switch." It lacks the power switch portion of the normal analog CD extraction device due to it's non conductive blue external coating. The blue coating does serve a travel purpose and that is it makes this paper clip stand out over others. I really hate it when I get my analog CD extraction device confused with other tech's analog CD extraction device.

The next figure is a paper clip tool that has nothing to do with CD extraction at all. This is a paper clip tool that was meticulously created with a pair of needle-nose pliers to make the monotonous tasks of bending pins on the Nintendo 72-pin cartridge connector pass quickly and smooth.

Another paper clip tool I made to hold IDE cables in place. In an ideal world, IDE cables are out of the way to allow for better air flow in a computer case. Sometimes that's easier said than done, but this can keep folded up IDE cables well...folded up. It's ten times manlier than using a bobby pin.

Figure 5 is neither something I made nor a paper clip, but I thought it would be interesting to include a real manufactured analog CD extraction device. This particular model comes with some CD/DVD drives, and I have found in most cases they are too big to be used in any other CD/DVD drive other than the ones that come with. Essentially, they are useless for most analog CD extraction needs, and on top of that they aren't very good ATX power switches either.

These are the paper clip tools I use; I'm sure other people have come up with other/better paper clip tools. I'd love to hear about them so feel free to leave a comment and preferably a picture.
