A pencil-centering assembly for use in pencil sharpeners or the like that includes a frame; a linking member rotatably mounted within the frame; a plurality of pencil contact levers, wherein each contact lever includes a top portion and a bottom portion, wherein the top portion of each pencil contact lever is adapted to engage the linking member, wherein the bottom portion of each pencil contact lever, in combination with the other pencil contact levers, defines a pencil insertion aperture having a center axis, and wherein the bottom portion of each pencil contact lever extends in to the pencil insertion aperture to about the same distance; and at least one biasing member in contact with the linking member, wherein the biasing member exerts force on each pencil contact lever by way of the linking member sufficient to bias each pencil contact lever toward the center axis of the pencil insertion aperture.

An electric pencil sharpener includes a power device. The power device is connected to two rotatable rubber wheels by a transmission mechanism. The two rubber wheels are located on two sides of the pencil to be sharpened, are rotated in opposite directions and closely fit a side wall of the pencil to be sharpened, to push upwards or downwards the pencil to be sharpened to move. A gap between the two rubber wheels is adjustable. The electric pencil sharpener further includes a rotatable cutter carrier assembly located below the rubber wheels configured to sharpen the pencil to be sharpened. The electric pencil sharpener can sharpen the pencil of different diameters, and has a sharpening process requiring no human participation, has a wide application and saves manual operation.

Devices, kits, and methods for making a carved crayon are provided. In one aspect, a crayon carving device includes a base, a pantograph armature coupled to the base, a crayon positioner, and at least one guide template parallel to the crayon positioner. The pantograph armature includes a motorized drive shaft with a drill tip for carving an outside surface of a crayon body, as well as a guide tip for tracing along a guide template that directs where the drill tip carves. In some embodiments, the guide template includes a stationary bridge support and a plurality of removable carving bucks that insert into one of multiple openings on the bridge support. The surface features of each of the carving bucks may be traced by the guide tip to generate a corresponding carving on the surface of a crayon body.

A sharpener for a writing instrument includes a receptacle, an entry assembly, and a cutter assembly. The entry assembly is coupled to the receptacle and defines an instrument opening. The entry assembly is configured to receive an end of the writing instrument through the instrument opening along an entry axis. The cutter assembly is configured to revolve about the entry axis in engagement with the entry assembly to sharpen the end of the writing instrument. The cutter assembly is removably engageable with the entry assembly at least by relative translation between the cutter assembly and the receptacle along the entry axis.

A dual cutter-carrier assembly that includes a rotatable carrier having a front portion, a rear portion, and a center portion, wherein the center portion defines an interior cavity that is adapted to receive a pencil to be sharpened; a first cutter pin mounted on the carrier, wherein the first cutter pin has a front portion having an annular groove formed therein; a first cutter rotatably and slidably mounted on the first cutter pin; a second cutter pin mounted on the carrier, wherein the second cutter pin has a front portion having an annular groove formed therein; a second cutter rotatably and slidably mounted on the second cutter pin; a contact plate mounted within the interior cavity at the rear portion of the carrier, having a first yoke mechanically coupled to the first cutter and a second yoke mechanically coupled to the second cutter, wherein the contact plate moves in the direction of a pencil that is being sharpened when the tip of the advancing pencil touches the contact plate, wherein the first and second yokes move the first and second cutters respectively in the same direction as the moving contact plate; and wherein, as the pencil advances to a predetermined distance through the interior cavity, the first and second cutters are adapted to move outward from the interior cavity and away from the tip of the pencil being sharpened.

A pencil sharpener holder attachment includes a plate having opposite front and rear sides and a continuous peripheral edge portion thereabout for attaching to an item worn by a user, a pencil sharpener holder body having front and rear housing portions at respective front and rear sides of the plate defining front and rear chambers open at rear and front sides of front and rear housing portions in communication with a central opening through the plate, and complementary interfitting structures interengaged with one another so as to attach the front and rear housing portions on respective front and rear sides of the plate such that the front and rear chambers form an elongated compartment storing a pencil sharpener extending through the central opening into both the front and rear chambers such that a pencil insertion orifice in the pencil sharpener aligns with an aperture in the front housing portion.

A reciprocating pencil sharpener has a shavings receptacle, a stationary member, a cutter and a ratchet mechanism. The cutter includes a blade secured to a blade holder. The ratchet mechanism is mounted between the stationary member and the cutter and allows the cutter to rotate relative to the stationary member in one direction only. When a user desires to sharpen a pencil, the user can keep the pencil in the hand and rotate the pencil in reciprocating rotation, thus obtaining the sharpened point of the pencil. Consequently, it is convenient for the user to apply a rotational force and a high efficiency of sharpening operation is achieved.

A dual cutter-carrier assembly that includes a rotatable carrier having a front portion, a rear portion, and a center portion, wherein the center portion defines an interior cavity that is adapted to receive a pencil to be sharpened; a first cutter pin mounted on the carrier, wherein the first cutter pin has a front portion having an annular groove formed therein; a first cutter rotatably and slidably mounted on the first cutter pin; a second cutter pin mounted on the carrier, wherein the second cutter pin has a front portion having an annular groove formed therein; a second cutter rotatably and slidably mounted on the second cutter pin; a contact plate mounted within the interior cavity at the rear portion of the carrier, having a first yoke mechanically coupled to the first cutter and a second yoke mechanically coupled to the second cutter, wherein the contact plate moves in the direction of a pencil that is being sharpened when the tip of the advancing pencil touches the contact plate, wherein the first and second yokes move the first and second cutters respectively in the same direction as the moving contact plate; and wherein, as the pencil advances to a predetermined distance through the interior cavity, the first and second cutters are adapted to move outward from the interior cavity and away from the tip of the pencil being sharpened.
