The weapon of choice for French gangster

Well, it was used by the french.

It's called an Apache Revolver, and it all folds and unfolds for different uses.

This is a french weapon. If you extend your arm infront of you, and grab the weapon like a brass knucke then you can shoot over your shoulders at your ennemies while running away from them. The brass knuckles allowed us you to punch any of our fellow frenchmen who refused to retreat and tried to block the passage, and the knife is here to rip through the labels of the wine bottles that were hidden in strategic place all along the retreat route.
This is a classic bit of history that is taught in our schools in France.
