The Blaster Edge is a un-common weapon. The Blaster Edge can be seen as a modern type of boomerang, always coming back to where it is launched. In order to use such a weapon, you can't be afraid of it. It might look dangerous when taking the Edge back, yet with a suffecient of training, you might become used to it. 

The Blaster Edge is launched by pulling onto the handle at the back. The Blaster itself is locked by a elastic. You can see this elastic as the red colour you see after you have launched. 

In order to upgrade the Edge, you must search for the items that has been given to you when reading the Weapons Magazines.
