Abstract: A safety cutter includes a handle and a recessed blade that is rotatably coupled to a head portion of the cutter. The blade is recessed relative to the opening of a channel or slot that receives the edge of a work piece or object to be cut. When brought into cutting engagement with an object to be cut, the blade rotates continually revealing (as it turns) a different cutting edge portion.

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 pocket knife (or pocket safety cutter) having a housing (or handle) and a folding/blade holder portion includes or is configured with one or more of, for example: a blade change mechanism with multiple safety features, a locking mechanism (for the folding/blade holder portion), and independently operable protective guards (for the folding/blade holder portion).

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.
