I love pens that do other things, then just right. I would love to have a display full of them.
Didn't the man form uncle have a radio pen or something like that.
In one of the later seasons of MacGyver, Mac, and Murdoc teem up, and Murdoc had a gass filled pen, that nocked some guy out. (plus, I think Mac turned a pen into a "Zip gun" one time.)
There is the Sonic pen from doctor who.
In the movie "Toy solders" One of the terrorists, used a pen from the headmasters desk, that telescoped out. (it was mint to be used as a pointer in the real word, but the terrorist, used it to beat one of the kids.) I have one of those pens. I could it at a yard sale.
In the real world I have seen Pens with knifes in them, torches/lighters, laser pointers, Clocks. Radios, microscopes, screw drivers, blow guns. etc. (I have a number of these items.
)
