Abstract
An assisted-opening knife has a spring tied to a front of a blade carrier and a movable slider assembly within a slot formed through the blade carrier, so that a blade can be rapidly extended by the elastic force without going through stepwise movement. An expanded portion of the slot engaging the slider assembly allows the blade to be received in a holder and ejected only when the slider assembly fully disengages from the expanded portion, thereby generating no sudden ejection of the blade. Additionally, a safety latch securely locks the blade when the blade is fully retracted. When the blade is fully extended, a stopper engages the slider assembly to prevent the blade from being retracted during cutting and stabbing. Accordingly, the assisted-opening knife addresses a solution to rapidly extend the blade for cutting and stabbing without compromising the safety considerations.
