Funny, this is exactly the rake I thought of when Wozzlock said soundwave. It is by no means a new design. It can be used to work on the same theory as a bumpkey, by raking it in and out of a lock bouncing tension you can trap pins above the shearline, or you could use it like this guy did and just place it in a lock with a similar biting to the shape. Just as effective. I like the idea of making new picks, and I have had success making rakes that are similar to key bitings that have been difficult for me in the past. Two of the most common key rakes are if you traced a line from the one pin to another it all the way down the key it would form a concave shape, the other exactly the opposite. I hope that's clear. Try it out, and see if you can't generate your own "cheat" rake. They can be highly effective. Just not very universal.
