A writing instrument including: a body extending longitudinally along a central axis; a resilient element fixed to at least one portion of the body. The resilient element of the at least one portion of the body is in one piece and is made of at least partially amorphous metal alloy.

A modular magnet writing instrument and hobby tool comprises a plurality of permanent magnet segments and a writing cartridge. Each magnet segment is magnetized axially. An aperture extends longitudinally through the entirety of each magnet segment. The writing cartridge has an elongate body, which is sized for coaxial insertion within a magnet segment, or plurality of magnet segments, such that the magnet segments are in sliding engagement with the elongate body. In operation, different combinations of magnet segments can be axially positioned on the elongate body, in a variety of like-pole and unlike-pole interactions, to produce a plurality of writing and hobby tool configurations.

A magnetized writing and amusement device. The device having a first end and a second end. Each of the ends having a magnet embedded with the interior. The magnetics allowing for the coupling of multiple devices together. The first end functions as a cap for the device and conceals a writing implement located within the internal structure of the device.

Cam faces 24a and 24b are continuously formed in a circle on upper and lower faces which are perpendicular to an axial direction of a rotatable cam 24 which constitutes a rotational drive mechanism 21. Elastic members 23b are formed integrally with a holder member 23 for rotatably supporting the rotatable cam 24 to extend in the axial direction, and the first fixed cam and second fixed cam 23c and 23d having a small number of cam faces at butts and tips of the elastic members are arranged to face each other via the upper and lower cam faces 24a and 24b of the rotatable cam 24. The rotatable cam 24 is retreated and moved forward in the axial direction by writing pressure applied to a writing lead to be rotationally driven in one direction and rotational motion of the rotatable cam 24 is transmitted to the writing lead.

A protective element for a writing tip of a writing instrument including a cap extending longitudinally along a central axis and configured to be fitted onto a body of the instrument, and a clip extending substantially parallel to the central axis from a first end fixed to the cap to a free end. The clip and the cap are in one piece.

A modular combination toy and desktop writing accessory apparatus comprising a plurality of structural elements each having at least one nodal connector portion to which a complementary connector portion of another structural element can be coupled. The structural elements can be assembled into a barrel-like form that is configured with a passageway for carrying a writing component of the invention. The writing component can be a pen, pencil, marker, crayon, eraser or the like. The modular combination toy and writing instrument has multiple functions in playtime as well as in everyday desk-bound activities.

The invention is embodied in a customizable writing instrument. In many respects, this customizable writing instrument is similar to an ordinary writing instrument. The big difference is that this customizable writing instrument comprises a removable second barrel. The removable second barrel (or sleeve) allows the guts of the instrument to remain housed in the first barrel so no writing instrument pieces get lost during customization of the second barrel.

The task is to provide an active stylus pen that can write on a written object, such as paper, like a ballpoint pen or a mechanical pencil.

An active stylus pen transmitting a signal to a chip provided at a tip of a refill of a ballpoint pen.

An apparatus for adjustably retaining an expendable medium for writing or drawing such as for a crayon core, a wax or oil based pencil (colored pencil) core, a chalk core or a pastel core includes a tubular barrel, at least one elongated arcuate body element, and a follower in abutting engagement with a portion of the body. The follower has a helical surface feature corresponding with spaced surface features of the body. The follower is configured to receive a non-writing end of an expendable core. The apparatus is configured such that the outer barrel of the apparatus can be made from a paper based material such as paperboard or other fibrous material that is more eco-friendly than other material such as plastics.
