Working COD Balistic knife

pinshape

This is my first project that involves mechanical components, but fortunately everything worked out in the end. The Ballistic Knife is a Special secondary weapon found in Call of Duty: Black Ops, Call of Duty: Black Ops II, Call of Duty: Black Ops: Declassified, Call of Duty Online and Call of Duty: Black Ops III. The Ballistic Knife functions as a secondary weapon. When fired or used for melee combat, it is capable of delivering a one-hit kill. A ballistic knife features a detachable blade that can be ejected to several yards by triggering a mechanism or operating a lever on the handle. Historically, spring-powered ballistic knives briefly gained notoriety in the United States during the mid-1980s after being marketed and sold commercially alongside other Western countries. This design is divided into multiple components for easy printing. To assemble it correctly, you will need three springs: two compression springs and one torsion spring. The blade has been split into two pieces to facilitate flat printing on your 3D printer. The case where the larger compression spring resides has also been divided into two parts, requiring attention to orientation during printing. The remaining components are relatively simple to print. I created this design as a challenge using mechanical elements and as a testament to my extensive gaming experience with Call of Duty, particularly with this iconic weapon. Steps to assemble it: 1. Print all the necessary files, noting that the blade requires two prints. 2. Source the required springs, which must be compact; their size will become apparent upon printing the design files. I personally used a spring from a pen for the button mechanism. 3. Before gluing the case components together, recommend attaching the trigger using a piece of filament or a thin metal wire and passing it through the torsion spring. Once this is secure, attach the button with its smaller spring. After that, you can assemble the remaining blade case pieces. 4. Insert the larger spring into the blade case followed by the blade itself; upon hearing a distinct click or seeing the mechanism engage, your weapon will be loaded – so exercise caution when handling it. 5. Optional: create a security pin using metal or other material for added safety.
