Abstract: A cutter apparatus includes a housing shaped to be hand-held, a blade holder configured to support a blade, and multiple actuators for extending the blade from the housing, the actuators including a safety actuator (e.g., a blade guard) that drives at least one of the other actuators while repositioning to extend the blade. The multiple actuators include, for example, a slider and a blade guard configured such that the slider when pushed forward repositions independently of the blade guard to extend the blade from the housing and such that the blade guard when pushed forward repositions the blade as the blade guard is deployed.

Abstract: A blade dispenser apparatus includes a body, a blade receptacle coupled to and repositionable in relation to the body, a blade holder coupled to and repositionable in relation to the blade receptacle, and an actuator coupled to the blade holder, the actuator being deployable for repositioning of the blade holder to dispense a blade or for disengaging a portion of the blade receptacle from the body allowing a user of the blade dispenser to access the blade receptacle.

Abstract: A cutter apparatus includes a housing with a blade carrier configured for holding a blade, and a handle coupled to the housing via an engagement interface configured to allow a user of the cutter apparatus to selectively interfit together the housing and the handle in multiple different cutter apparatus configurations, wherein the engagement interface includes a coupler configured to permit the housing and the handle to be repositioned further apart in a housing/handle reconfiguring mode in which the coupler permits the handle to be rotatably repositioned in relation to the housing or vice versa while substantially limiting longitudinal movement of the housing relative to the handle.

Abstract: A cutter apparatus includes a housing configured for gripping by a hand, a blade holder and/or blade coupled to the housing, a guard secured to the housing, and a handle coupled to the housing via an engagement interface configured to allow a user of the cutter apparatus to selectively interfit together the housing and the handle in multiple different cutter apparatus configurations including a pair of configurations in which the guard, in relation to each configuration, faces the blade from right and left sides, respectively, of the cutter apparatus.

Abstract: A cutter apparatus includes a housing shaped to be hand-held, a blade carrier repositionable in relation to the housing and configured to support a blade thereon, and multiple cut guides independently operable to drive the blade carrier for extending the blade from the housing.

Abstract: A blade dispenser apparatus includes a body, a blade receptacle coupled to and repositionable in relation to the body, a blade holder coupled to and repositionable in relation to the blade receptacle, and an actuator coupled to the blade holder, the actuator being deployable for repositioning of the blade holder to dispense a blade or for disengaging a portion of the blade receptacle from the body allowing a user of the blade dispenser to access the blade receptacle.

Abstract: A cutter apparatus includes a housing configured for gripping by a hand, a blade holder and/or blade coupled to the housing, a guard secured to the housing, and a handle coupled to the housing via an engagement interface configured to allow a user of the cutter apparatus to selectively interfit together the housing and the handle in multiple different cutter apparatus configurations including a pair of configurations in which the guard, in relation to each configuration, faces the blade from right and left sides, respectively, of the cutter apparatus.

Abstract: A cutter apparatus includes a housing with an opening, and a blade carrier coupled to the housing to permit rotational movement of the blade carrier between a refracted position and a deployed position and to permit movement of the blade carrier toward a distal end of the cutter in response to a cutting edge of the blade coming into contact with a workpiece, the blade carrier being coupled to the housing and configured for holding and deploying a blade at a plurality of selectable blade depths and for preventing the blade carrier from rotating back into the housing when the blade carrier is deployed at any of the selectable blade depths and advanced to a cutting position.

Abstract: A holster for a cutter apparatus includes a body sized to receive a cutter apparatus therein and configured to provide a cutter-holster interface that causes a component of the cutter apparatus to reposition in relation to a housing of the cutter apparatus as the cutter apparatus is pushed into the holster. The component (e.g., a blade depth selector) is automatically repositioned to a safe (or other predetermined) position in response to the cutter apparatus being pushed into the holster.

Abstract: A cutter apparatus includes a housing with an opening, a blade carrier coupled to and repositionable in relation to the housing, an actuator for repositioning the blade carrier to a deployed position, the blade carrier repositioning toward the deployed position in response to movement of the actuator toward an actuator blade deployment position, a push rod that is repositionable within the housing and coupled to the blade carrier such that a location of one or more portions of the push rod in relation to the housing determines the blade depth extending from the opening of the housing when the blade carrier is deployed, and a blade depth selector coupled to the push rod such that a user of the cutter apparatus can set the location to provide a desired blade depth by selectively repositioning the blade depth selector in relation to the housing.

Abstract: A cutter (or other hand tool) includes a housing with a handle that is sized and shaped to fit in the palm of a hand, the housing being configured to provide multiple hand-housing interfaces favorable to natural accommodation of the hand while using the cutter (or other hand tool). The hand-housing interfaces can include one or more interfaces that accommodate the hand at a neutral wrist position.

Abstract: A cutter apparatus includes a housing with an opening, a blade carrier coupled to the housing and repositionable in relation to the housing, and an actuator repositionable in relation to the housing and coupled to the blade carrier such that movement of the actuator to an actuator blade deployment position repositions the blade carrier toward the opening and provides mechanical advantage in deploying the blade or maintaining the blade in a deployed position.

Abstract: A cutter apparatus includes a housing, a blade holder coupled to the housing, and a blade storage assembly including blade storage compartments, one of the blade storage compartments being configured to serve as a cover for another of the blade storage compartments. The housing includes a hood and the blade storage assembly is coupled to the hood (e.g., secured to the underside of the hood) such that the blade storage assembly is made accessible to a user of the cutter apparatus by repositioning the hood in relation to another portion of the housing.
