What is Open bullet/Black bullet?

Hello, I have tried googleing but no results or anything, as the title says, can someone explain what Open bullet/Black bullet is and how they work. Are they just a sort of cracker tool and why should you use them and why are they good/bad? 

Appreciate every single answer.

Best regards zveuse, stay zveused
