Abstract: Embodiments of the disclosure can include writing instruments, nibs for writing instruments, and methods of making the same. In one embodiment, the writing instrument includes a reservoir; an ink solution comprising a pigment, the ink solution being housed within the reservoir; a nib disposed at an end of the reservoir and plugging an opening of the reservoir such that the reservoir is closed, wherein a tip of the nib extends outside of the reservoir; and a filament extending within the reservoir, the filament being in fluid communication with a portion of the nib within the reservoir, such that the ink solution travels along the filament and through the nib, by capillary action, wherein the nib and filament are formed such that no more than 50 percent of the pigment present in the nib and filament flow into the reservoir outside of the nib and filament when the writing instrument is stored with the nib up for a period of one day.

Abstract: A side-knock type mechanical pencil comprising a body with a side-mounted knock button coupled to the body of the mechanical pencil and adapted to slidingly engage with a lead tube with a frustoconical hub for translating the motion of the knock button actuation to linear extension of the lead.
Abstract: 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.
