Abstract: A double spring folding knife includes a handle having a curvilinear groove on an interior surface, and a knife blade. The knife blade has a locking pin that extends away from a first side of the knife blade and is configured to slidingly engage the curvilinear groove. A bow spring is fixed to the handle and is orientated to interact with the locking pin in order to exert a force on the locking pin during a portion of travel along the curvilinear groove. The knife also includes a coil spring having a first end fixed to the handle and a second end fixed to a second side of the knife blade, where the coil spring is configured to exert an opening force on the knife blade after the locking pin has traveled past the bow spring along the curvilinear groove.

Abstract: A flashlight stun gun device includes a cylindrical housing having a power source coupled to discharge circuitry, where the discharge circuitry has a first lead and a second lead. In addition, a light emitting source is secured to a top end of the cylindrical housing and is coupled to the power source. A collar is secured to the top end of the housing and around the light emitting source. First and second electrodes are embedded in a first portion of a top edge of the collar and have a first gap therebetween to generate an electric arc across. Third and fourth electrodes are embedded in a second portion of the top edge of the collar opposing the first pair of electrodes and have a second gap therebetween to generate an electric arc across. The electrodes are electrically coupled together in series when the discharge circuitry is activated.

Abstract: A stun gun with a knuckle guard is disclosed. The stun gun is configured to fit and be held firmly within a palm of a user's hand. A knuckle guard is disposed on the stun gun and is configured to cover the user's knuckle when the stun gun is being gripped by the user's hand. In addition, the stun gun includes a trigger that is disposed on a front portion of the housing and is used to activate the stun gun by pushing down on the trigger with the user's finger. Electrodes are mounted above the knuckle guard and are adapted to discharge an electric shock when the trigger is activated. A rear portion of the stun gun also includes a pair of pointed projections that are adapted to be used to strike the assailant to cause injury.

Abstract: A stun gun with finger grip is disclosed. The stun gun is configured to fit and be held firmly within a palm of a user's hand and easily gripped with the user's fingers. A trigger is disposed within a finger grip aperture of a front housing and rear housing of the stun gun, where the trigger causes the stun gun to discharge an electric shock through electrodes mounted above the finger grip aperture to stun an assailant. The finger grip aperture is configured and placed on the stun gun to receive the user's finger therein when the stun gun is being gripped by the user's hand. The finger grip aperture protects the user's finger and prevents the assailant from easily dislodging the stun gun from the user's hand. The user's finger may be placed completely through the finger grip aperture to provide a firm grip on the stun gun. In addition, in a struggle with the assailant, the user's finger can remain firmly on the trigger and continue to depress the trigger to repeatedly shock the assailant.
