These are a handy thing to have around in all sorts of situations, you really owe it to yourself to have a pair.
That being said, bogota rakes were invented by Raimundo, if you want the real thing, why not head over to Serepick and order up a pair. While this design has been disseminated all over the web, I owe all credit for the shape and method to Raimundo.
I have not seen anyone else make them out of bra underwire. So, I wanted to share what I had learned from whipping up a few sets of my own.
This instructable was put together mainly for the folks over at http://www.reddit.com/r/lockpicking
, hope you found it useful! Here is a video of them working, sorry about the poor quality, it's an hd cam, I'm kind of miffed about the 360 nonsense.
