Spring-powered ballistic knives gained brief notoriety in the United States during the early to mid-1980s, often marketed as the “KGB Ballistic Knife” despite lacking any evidence of actual use or issuance by the Soviet Union’s KGB, who likely found the design impractical. Since the 1980s, several U.S. companies have produced variations of these knives in limited runs, mostly for their novelty or collector appeal. There has been no documented case of these knives being used in a violent crime.
Ballistic knives, a topic surrounded by intrigue and controversy, have captured the attention of both weapon enthusiasts and lawmakers around the world. At its core, a ballistic knife is a specialized combat knife with a detachable blade that can be ejected to a limited range by the press of a trigger or switch, typically powered by a spring mechanism or compressed air. This unique capability distinguishes it from conventional knives and has led to a variety of uses, both practical and recreational.
The primary advantage of ballistic knives lies in their ability to engage targets from a distance, of approximately 5 meters (16 feet), with greater force than a conventional knife thrust or throw. A distinguishing feature is their capacity to project the blade at speeds reaching 63 km/h (39 mph), significantly augmenting their effectiveness compared to traditional throwing knives. However, once discharged, the device becomes inoperative, necessitating the possession of multiple knives. Upon firing, a ballistic knife blade can penetrate wooden boards to depths of 35–40 mm, ample for reaching vital organs.

Despite their unique capabilities, ballistic knives exhibit drawbacks. Prolonged compression of the spring mechanism can lead to residual deformation, rendering them unsafe for extended periods in a cocked position. Additionally, they have a short effective range and are sensitive to contamination and corrosion due to close tolerances between moving parts. Moreover, the high speed of blade ejection poses a risk to users if mishandled.
Ballistic knives feature intricate designs and mechanics that distinguish them from conventional edged weapons. These knives operate on a launching mechanism capable of projecting the blade with considerable force.

Typically comprised of a handle housing the launching mechanism and a detachable blade, ballistic knives are constructed from durable materials chosen for their strength and weight characteristics. High-grade steel is often favored for blades due to its strength and edge retention properties, while handles may incorporate metals, hard plastics, or composites for durability and grip.

Ballistic knives employ various launching mechanisms, commonly spring-loaded systems. In a dormant state, the blade is secured within the handle by a locking mechanism. Activation, typically initiated by a button or lever, releases the lock, allowing the compressed spring to propel the blade forward. Some models utilize compressed air or gas for blade ejection, offering alternative means to achieve similar results.

Ballistic knives have seen various iterations and improvements over the years, with each design aiming to enhance performance, safety, and ease of use. Some models incorporate features like adjustable power settings, allowing users to control the force behind the blade’s ejection. Others focus on compactness and concealability, catering to the needs of those who prioritize discretion. Despite these variations, all these knives share the defining characteristic of a detachable, projectile blade, making them a unique category of weaponry.

Spring-Operated: The most common mechanism, where a coiled spring inside the handle is compressed and released to propel the blade.
Gas-Driven: Utilizes compressed gas to eject the blade. These models can sometimes offer adjustable power levels for blade ejection.
Material Variations: Handles can be made from a variety of materials including but not limited to metal, plastic, or composite materials, affecting the weight and grip of the knife.
Ergonomic Designs: Some models feature ergonomically designed handles for better grip and control during use.
Safety Mechanisms: To prevent accidental deployment, ballistic knives may include safety locks or buttons.
Integrated Tools: Variations include adjustable power settings, compact and concealable designs, and integrated tools such as screwdrivers or bottle openers.
Civilians generally cannot own ballistic knives in many countries, including the United States. The Federal Switchblade Act, amended in 1986, specifically prohibits the possession, manufacture, sale, or importation of ballistic knives. This law applies across the entire U.S., although additional restrictions or allowances might vary by state.
In other countries, similar restrictions are often in place due to the perceived danger and potential for misuse associated with these weapons. It’s important to check local laws and regulations if you’re considering acquiring any type of specialized knife to ensure compliance with legal standards.
The legal status of ballistic knives varies widely across jurisdictions, with regulations ranging from strict prohibitions to more permissive approaches. In the United States, federal law prohibits their manufacture, sale, and possession, with additional state-level restrictions. Similarly, countries like the United Kingdom, Canada, and Germany classify these knives as prohibited weapons, while others may regulate them under broader weapon laws.

Overview of Legality in Various Countries
Ballistic knives are subject to a wide range of regulations that differ significantly from one country to another. In some jurisdictions, they are classified alongside conventional knives and are regulated under general knife laws. However, due to their potential as projectile weapons, many countries have enacted specific statutes or regulations that address these knives directly. For instance, in the United States, federal law prohibits the manufacture, sale, and possession of ballistic knives, with additional restrictions varying by state. In contrast, other countries may have more lenient laws or even no specific mention of this type of knife, treating them under the broader category of weapons or prohibited items.

Changes in Legal Status Over Time
The evolution of laws concerning this type of knives reflects changing perceptions of their threat level and public safety concerns. Initially, when ballistic knives first appeared on the market and in public awareness, there was little to no legal recognition or regulation. As their presence became more noted, particularly with sensationalized accounts of their use in criminal activities or as tools for espionage, lawmakers began to scrutinize their status. Over time, this led to a patchwork of legislation, with some countries tightening restrictions, while others maintained a more permissive stance. The legal landscape continues to evolve as new considerations emerge, such as advancements in knife technology and shifts in societal attitudes towards weapons and self-defense.

All the comments agree that ballistic knives appeared in recent times (the 70s and later), however I remember seeing an old TV series, in the black and white era, where a character who played an Indian sepoy killed a soldier with a ballistic knife that in the series was called a “jumping knife.” I don’t know why, but I think versions may have existed before 1970.
