Abstract: An electric knife including a knife body, forming a handle housing an electric motor, and a blade holder, received in the handle, carrying a blade and maneuvered by the motor via a device for transforming rotary movement of the motor into alternating movement of the blade holder. The knife body includes a fixed shaft perpendicular to the blade on which the blade holder is mounted and which is positioned so that the blade holder is moved in rotation and to-and-fro relative to the fixed shaft by the motor to impart an oscillatory movement to the blade.

Abstract: A dispensing container for flat objects (1), such as boxcutter blades, includes a container body (2) in which is housed a sliding support (3) designed to move between a rear face (4) and a front face (5) of the container, for which the objects are stacked between the sliding support (3) and the front face (5) of the container, the sliding support pushing the objects (1) against the front face under the action of at least one elastic element (6, 6?), the elastic element being designed to pull the sliding support from the rear face to the front face of the container.

Abstract: The purpose of this invention is a long-blade cutter with adjustable blade extension and retractable blade guard including an elongated body in which the blade can retract, a slider capable of moving the blade in its plane, a blade holder/loader within which the blade can slide, characterized in that it also includes a safety guard made up of an extended element that can cover the edge of the blade over its full length, arranged movable between a fully retracted position inside the body and an extended position over the entire length of the blade at its position of maximum extension, an elastic recall link mechanism interposed between said safety guard and the slider, means of driving the guard by said slider and a push-button for disengaging said means of driving.

Abstract: A knife includes a casing and a blade which can have two positions, an extended position in which the blade projects outside the casing and a retracted position in which the blade is disposed within the casing, a blade carrier to which is connected the blade, a housing on which is slidably mounted the blade carrier and that is removably mounted within the casing, and a finger piece-pusher mounted slidably on the casing to move forwardly the blade carrier to place the blade in a cutting position. The blade carrier and finger piece-pusher are returned to the retracted position by return springs. Components are provided to secure the finger piece-pusher and the blade carrier together to place the blade in the extended position. The components are uncoupled by a conjoint action of rotation and extraction of the blade carrier relative to the finger piece-pusher, resulting from the cutting action.

Abstract: The object of the invention is a cutter with a monoblock blade carrier with securement and release of the blade by pressure, characterized in that said blade carrier (1) is made by molding from a semi-rigid plastic material and comprises two substantially flat shells (1a, 1b) folded facing each other, connected by a thin bridge (2) and defining between them a recess for the reception of a blade (3) open at least on its sides, one of the portions (1a) comprising on its internal surface a projection (10) adapted to penetrate a hole (5) in the blade (3) so as to trap it in said recess (8, 8a) and being, adjacent this latter, deformable by pressure (P) so that, by a lever effect, said projection (10) moves away from the opposite surface of the other shell (1b), thereby permitting the free passage of the blade (3) outside its recess (8, 8a).

Abstract: The object of the invention is a knife comprising a casing (2) and a blade (6) which can have two positions, a first so-called extended position, in which the blade (6) projects outside the casing (2), and a second so-called retracted position, in which the blade (6) is disposed integrally within the casing (2), characterized in that it comprises a blade carrier (4) to which is connected the blade (6), a housing (3) on which is slidably mounted said blade carrier (4) removably mounted within the casing (2) and a finger piece-pusher (7) mounted slidably on the casing so as to move forwardly said blade carrier (4) so as to place the blade in cutting position, said blade carrier (4) and finger piece-pusher (7) being returned to the retracted rest position by return springs (8-11), and in that means (7b, 16, 17) are provided to secure the finger piece-pusher (7) and the blade carrier (4) together to place the blade in said first position, said means being uncoupled by a conjoint action of rotation and extraction

Abstract: A cutter type knife comprises a hollow handle, a housing in said handle adapted to receive a removable blade fixed in position relative to said handle and projecting at least partly from one end of said handle. A blade cover is slidably disposed within said handle to be movable axially between a first position in which it is retracted into said handle and a second position in which it is adapted to surround or cover the part of said blade projecting from said handle. Means are provided for moving said blade cover between said first and second positions consisting of a trigger pivoted to said handle and a transmission mechanism is adapted to convert rotation of said trigger into axial displacement of said blade cover within said handle, whereby when said trigger is depressed said blade cover is moved to said first position.

Abstract: A cutter type knife having a handle with a blade disposed to slide axially within the handle. Elements are provided for manually deploying the blade and automatically retracting the blade when a manual operating element is released. The manual operating element is a member adapted to be at least partially retracted into the handle. An additional part is adapted to convert movement of the aforementioned member into axial movement of the blade within the handle. In this way, retracting the aforementioned member deploys the blade. Also provide is a latch or lever for initially impeding retraction of the aforementioned member, whereby an initially greater force is required in order to begin retracting the member and thus deploy the blade.
