That actually appears to be a "batarang" rake opposite the half-diamond. It should work on just about any lock that you could use one of those individual picks on, it is just a '2 in 1' or double-ended pick so that you get twice as many different pick types for a given number of tools in a kit. The half-diamond has a ton of different uses in both pin tumbler (including dimple-style) and wafer locks. The batarang rake can be used on most wafer and pin tumbler locks but it is not very popular due to a weakness in the tip which can cause the head to break off the shaft under stress. The handle (such as it is) does not look like it would be terribly comfortable for long use or with high-resistance locks which require heavy pressure on the pick.
This lock pick is just another diamond. You can call her Peggy. She is curvy and slender. She likes to be pushed up and be roughed up once in a while (batarang side) , although her other side (the diamond) at times requires intelligence and finesse to work with her.
Looks like a general purpose snake rake on one end and a diamond on the other. The snake is used mainly for raking and the diamond can be either a lifting (picking) tool or used as a kinetic (raking) tool.
Lots of folks use these to "rake into a false set" before they start single pin picking.
I recieved one of these in a southord kit. It hurts my fingers after a short period. Im working on a pick handle that uses a set screw to hold changeable tips. Im planning on making this pick into two tips so that its put to use.
