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.
