Don’t worry! This is not a gun but a knife. The Pew Pew Mini Automatic Knife is a 6.5 inch automatic knife with a handle designed to look like a rifle fit with a magazine and trigger. This thing can’t fire, but it is an automatic knife. That means there is a button on the front of the handle that causes the blade to swing out automatically. There is another silver lever on the front of the handle that moves from side to side. This is the lock function. When the lever is to the left the knife is unlocked and if the button is pressed then the blade will deploy. If the lever is to the right then the knife is locked and the blade will not deploy even if the button is pushed. The blade on the Pew Pew Mini Automatic Knife is 2.75 inches so if you are looking for a small knife to carry with you then this is the knife for you. Overall Length: 6.5 Inches. Weight: 0.15 lbs.
