A writing instrument that comprises a writing instrument base and a focus tool is provided. The writing instrument base includes a marking system coupled with a barrel. The marking system is configured to provide writings on a writing medium, such as paper. The focus tool is coupled with the writing instrument base. The focus tool is configured to blend in with the writing base. The focus tool includes a device that engages a user's senses and reduces the negative impact of attention deficit disorders when used by the user. The fidget tool stimulates the user's vestibular system and proprioceptive senses through one or more of the following: movement, sound, smell, visual, and tactile action. The fidget tool may be discreet such that the tool is hidden or not viewable when not in use.

Disclosed herein embodiments for a writing instrument operable to spin around its lateral axis while held on opposite sites. An embodiment includes a barrel, a first bearing coupled to an interior side of the barrel and a second bearing coupled to an interior opposite side of the barrel. A first stub protrudes from a side of the barrel, the stub being in contact with the bearing so as to allow the stub to spin around a lateral axis of the barrel, the lateral axis comprising an axis perpendicular to a length of the barrel. A second stub protrudes from an opposite side of the barrel, the second stub being in contact with the second bearing so as to allow the second stub to spin around the lateral axis of the barrel.

Writing equipment includes a cylinder-shaped body having a lead and a lead tank, and an arch-shaped scale on which scale marks are printed, wherein the scale is coupled with the body detachably, and wherein the scale is formed with the particular angle, which is same as that of a curve of the cylinder-shaped body.

A writing implement assembly for writing on a writing surface includes an ink dispenser is configured to be attached to a finger. The ink dispenser discharges ink when the ink dispenser engages a writing surface. A grip is removably attached to the ink dispenser to facilitate writing with the ink dispenser.

A refill friendly pen body that is configured to adapt to a refill cartridge of various dimensional parameters. An adjustment cylinder is adjustably carried within a barrel to adapt the pen body to a length of the refill cartridge. A grip end of the pen body is configured with an internal collet to compressively engage with a forward end of the cartridge across to retain the forward end of the cartridge in a writing position. The pen body may also be provided with a cap to selectively cover and uncover the writing tip.

Example clippable multi-tone whistles, as well as systems and methods for manufacturing the same are described. An example clippable multi-tone whistle may comprise: a clip attached to a whistle body. The whistle body comprises a flat surface under the clip; a first opening configured to allow air flow to come into the whistle body; and on the flat surface a second opening configured to allow air flow to come out of the whistle body. The second opening is at least partially blocked by the clip, which controls direction of one or more air flows coming out of the second opening. The whistle part is configured to generate a plurality of different sound tones in accordance with user finger movements around the clip and the second opening. The whistle may further comprise a glass breaker, a length scale, and a bolt action switch, which may function as a fire starter.

A pen includes: a shank; an ink tube inside the shank; a first tip member connected to a distal end of the shank; a second tip member connected to a distal end of the first tip member; and a bent tubular member including a proximal end section, a middle section, and a distal end section. An axis of the middle section is arranged at a first angle relative to a central axis of the shank. The axis of the middle section is arranged at a second angle relative to an axis of the distal end section, the second angle being in a range of 45 to 90. The axis of the distal end section is arranged at a third angle relative to the central axis of the shank.

A writing instrument includes a barrel and a cap capable of being assembled with and secured to the barrel. The barrel carries a writing instrument. The cap carries a clip. A free end of the clip includes a detent that can be received by a corresponding indentation of an exterior surface of an external portion of the barrel when the cap is assembled with the barrel. The detent of the clip and the indentation of the barrel are capable of securing the cap and the barrel in their assembled relationship. The writing instrument may be compact. Methods of using a writing instrument include securing a cap of the writing instrument to a barrel of the writing instrument by causing a detent of a free end of a clip of the cap to engage a corresponding indentation of an exterior portion of the barrel.
