7. A safety utility knife, comprising:
a blade carrier repositionable from a safety orientation to an intermediate orientation, and from the intermediate orientation to a cutting orientation;
a blade positioned within the blade carrier;
a blade carrier hinge initiating portion fixed to the blade carrier;
a blade carrier biasing spring, wherein the blade carrier biasing spring biases the blade carrier to the safety orientation;
an actuator, wherein the actuator is repositionable between a non-actuating orientation and an actuating orientation;
an actuator biasing spring, wherein the actuator biasing spring biases the actuator to the non-actuating orientation; and
a hinged link interconnected between the blade carrier and the actuator, wherein the hinged link includes a blade carrier link portion hingingly connected to an actuator link portion, and wherein the blade carrier link portion is rotatably connected to the blade carrier wherein, when the blade carrier is in the safety orientation, the blade carrier hinge initiation portion is not engaged with the actuator link portion and the blade carrier link portion, and wherein, when the blade carrier is in the cutting orientation, the blade carrier hinge initiating portion engages the actuator link portion to hinge the blade carrier link portion with respect to the actuator link portion.
