A cap for a pencil, comprising an insertion opening, at least two internal retainer ribs which are distributed angularly and uniformly about a central axis of the cap. The at least two internal retainer ribs positioned close to the insertion opening and configured to cooperate with an unsharpened portion of the pencil, and a stop surface which is configured to cooperate with a sharpened end of the pencil.

Provided are a mechanical-pencil cap serving as a touch-pen tip and a pencil-lead sharpener, and a mechanical pencil having the mechanical-pencil cap. The mechanical-pencil cap includes a front fixing part (11b) for the touch-pen tip formed in a shape of a truncated conical recess, and a pencil-lead sharpener functioning part (11c) provided to be opposite to the front fixing part (11b) for the touch-pen tip, and connected to the touch-pen tip (11f) formed to surround an outer circumference of a touch-pen tip fixing member (11e). This enables an input operation into a mobile terminal, such as a smartphone or a smart pad having a capacitive touch screen, to be performed in a touch manner, and allows a pencil lead inserted into a pencil-lead insert container and ejected out when in use to be conveniently sharpened without the necessity of separating the pencil lead.

An extension for pencils with wearing leads, formed from a thin-walled hollow profile. The inner cross section is adapted to the shape of a pencil. One or more slots of appropriate length in the longitudinal direction at an end of the extension where the tapered end of the pencil is located and a slight linear reduction in the cross section approximately over the length of one or more slots. Longitudinal raised sections in the form of triangular, square, and/or semi-circular prisms, directed inwardly. The height of the raised sections may increase in the direction of insertion of the pencil and dig into the pencil slightly when the pencil is inserted. The height of the raised sections is reduced linearly to zero at the end of the extension where the pencil is inserted. Inwardly bent or protruding retaining springs arranged on the inner surface of the extension.

A banana shaped writing device; the banana shaped writing device includes a body, a lead, a stem, a peel, and a metal clip. The banana shaped writing device is useful for allowing a user to peel the writing device and provides a cushioned finger hold. Further, the banana shaped writing device is helpful to teach children who are beginning to write the proper finger positions to write.
