Safety cutter with blade depth selector/interlock mechanism

A cutter apparatus comprising:

• a housing;
• a blade carrier configured to support a front blade, the blade carrier being coupled to and repositionable in relation to the housing;
• an auxiliary tool configured to be deployable from another portion of the housing;
• a blade guard mechanically coupled to the housing and configured to be extended and retracted adjacent to the front end of the housing;
• and
• a selector repositionable in relation to the housing and configured for mutually exclusively facilitating user-controlled actions of setting a maximum blade depth to which the front blade is extendable from the housing and activating the auxiliary tool;
• wherein the blade carrier and the selector are configured such that a portion of the selector engages a portion of the blade carrier when the front blade repositions to the maximum blade depth;
• wherein the selector includes one or more engagement portions that are repositionable along a path and configured to selectively engage stop surfaces;
• wherein the blade carrier includes or is coupled or connected to an actuator that is repositionable in relation to the housing;
• wherein the actuator and the blade guard are configured such that the actuator when pushed forward repositions independently of the blade guard to extend the front blade from the housing.
