Ball for double sided wafer lock so you dont have to pull out the pick and turn it when you pick the lock, you can also use a wide snake or what ever serves you.

The other rake tools are just for different styles of raking certain people prefer and find more success with. Most of us here don't use rakes too much because we like SPP method with a short hook. The key extractor is just that, a broken key extractor.
