Origins of Switchblade Knives

Switchblades have a centuries-old history. Europe invented spring-loaded blades in the 18th century. Switchblade knives became popular in Italy in the 19th century.

Italian tradesmen called these early prototypes “stilettos” due to their slim and pointed shape.

Side-Open Switchblades

Side-opening switchblades open from the handle’s side. A button or switch releases the blade and opens it. Side-opening switchblades are popular for their convenience.

How Does a Switchblade Knife Work?

Switchblade knives use a simple yet effective system for quick blade deployment. Switchblades have a blade, handle, spring, and locking mechanism.

The handle conceals the knife’s blade when closed. The spring releases when a button or switch is pressed, extending and locking the blade.

Locking the blade prevents inadvertent closes. A lever or button releases the lock and allows the blade to fold back into the handle to close the switchblade knife.
