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.

A blade retention mechanism that includes a body and a catch. The catch is configured to engage a bit. A knurled nut is configured to engage the catch and the body such that it is movable. When the nut is moved between a first position and a second position the catch moves between a first position and a second position. A v-groove is formed in the body and is configured to receive and retain a bit when the catch is in the first position.

The present invention generally relates to cutting devices. Specifically, the present invention relates to a deburring cutter device. In some examples, the deburring cutter includes a handle module, a blade, and a blade cover. In an exemplary embodiment of the present invention, the handle module includes a blade holder configured with a blade cavity having walls which are adapted to reversibly secure the blade, allowing the blade to be selectively removed.

A utility knife constructed of a lower shell (102), an upper shell (104), a retaining knob (106) and a hinge pin (108). The hinge pin (110) provides a high-strength connection between lower shell (102) and upper shell (104). Retaining magnets (110) and (112) retain steel utility blades in place when shells (102) and (104) are separated from one another. According to one embodiment, the retaining magnets (110) and (112) are permanent magnets made of an alloy of neodymium, iron and boron.

A bolster-actuated folding knife may have a folding knife blade whose opening and closing is controlled by an actuator on the knife's handle. This bolster-actuator may rotate in either of two rotational directions about the same pivot as the knife blade. When a user rotates the bolster-actuator in one direction, the bolster's pin may impinge via direct contact with the knife blade forcing the knife blade fully open. When a rotates the bolster-actuator in the opposite direction bolster-actuator rotation and thus bolster pin deflection may cause the knife's locking tab to disengage from a cutout in the knife blade, unlocking the knife blade from its fully locked-open position and urging the knife blade to close. Thus, the bolster-actuated folding knife may provide a convenient means to open and close a locking, folding knife with only one hand, and without substantial interference with the knife's aesthetic appeal.

Embodiments of the invention are directed to a folding or butterfly knife that provides for easily changing a blade or other tool on the knife. The knife includes a first handle component; a second handle component; and a knife component. The knife component comprises a blade integrally connected to a tang, pivotally secured to the first and second handle components by an attachment section. The attachment section comprises a first plate; a second plate; an inner plate located between the first and second plates; and a kicker lever for removing and replacing the blade in the knife segment, the kicker lever comprising a protrusion and a kicker located at an upper end of the kicker lever and a lever stop located at a lower end of the kicker lever for defining the movement of the kicker lever.

The present disclosure provides a switch-actuated multi-tool apparatus. The switch-actuated multi tool apparatus includes one or more cutting tools. In addition, the switch-actuated multi tool apparatus includes a housing module. The housing module encloses the one or more cutting tools in a non-functioning state and the housing module has a grip for holding the switch-actuated multi-tool apparatus when the one or more cutting tools is in a functioning state. Further, the switch-actuated multi tool apparatus includes a switch positioned within or around the housing module. The switch actuates the one or more cutting tools. Furthermore, the switch-actuated multi tool apparatus includes a detachable attachment module positioned anywhere around periphery of the housing module. The detachable attachment module allows one or more accessories to be detachably connected to the switch-actuated multi-tool apparatus.
