A pen structure with a glass smasher has the glass smasher mounted at the front end of a pen. When a user holds the pen and presses the front end (i.e., the smashing cone) of the smashing rod of the glass smasher forcibly against a glass obstacle, an impact block will strike the rear section of the smashing rod vigorously such that the smashing cone is instantly driven to smash the glass obstacle. A ballpoint/rollerball refill is detachably provided in the pen and is at least 6 cm long in order to contain enough ink. The overall length of the pen is at least 10 cm so that the pen can be easily held while the user writes or draws with the ballpoint/rollerball tip and while the user applies a force to a glass obstacle through the front end of the smashing rod to smash the glass obstacle.

A thermochromic writing instrument including a writing body, storing a thermochromic ink therein, stored in a barrel; an operation body provided in the barrel to be operated to longitudinally move the writing body; a nib of the writing body configured to be capable of appearing from a front end of the writing instrument, wherein the writing instrument 1 further includes a friction unit, for rubbing handwriting in the thermochromic ink and capable of thermally changing the color of the handwriting by frictional heat generated at that time, and at least one clip body as the operation body, the friction unit 10 is provided at a rear end of the barrel, and the clip body is provided in an area other than the rear end of the barrel.

The writing instrument comprises a first barrel, a second barrel, and a self-blocking assembly system for assembling the first barrel with the second barrel. The self-blocking assembly system includes a blocking device for blocking the first barrel with respect to the second barrel in a longitudinal direction and a locking device for locking the blocking device. The locking device includes a slot formed in the first barrel and two ramps carried by the second barrel. The slot extends in the longitudinal direction and has two longitudinal edges. The two ramps are configured to part the two longitudinal edges of the slot progressively in a circumferential direction as the first and second barrels are assembled. A window extends in the longitudinal direction formed between the two ramps, and a lateral button is housed at least partially in the window that includes guide surfaces for guiding the lateral button.

A writing, drawing, marking and/or painting utensil or cosmetics implement or input device for contact-sensitive surfaces, wherein the utensil/implement/device includes at least one shank element made of plastics material or a plastics-containing wood substitute. The at least one shank element has a surface, or in that the at least one shank element has a surface which is sheathed in a material layer having a cover surface. The surface of the shank element or the cover surface of the material layer is in the form of a haptic and/or non-slip layer. The haptic and/or non-slip layer has a structure formed in one piece with the shank element and/or the material layer. The structure is formed by corrugation.

Representative implementations of devices and techniques provide a tactical pen that may include various useful features and components, according to various embodiments. In the implementations, the tactical pen is comprised of multiple components (e.g., two or more sections) which may be coupled together and which may be sealed with one or more seals to provide moisture or humidity protection to the contents of the pen. For example, in addition to an ink pen refill (e.g., ball-point pen refill), the tactical pen may include one or more cavities or compartments to store items, a sharp implement, as well as one or more additional tools or implements.

A writing implement includes a housing for receiving a refill, an operating side and a writing side. An adjustment mechanism in the housing has a guide bushing and a cam pin concentrically arranged therein and spring-loaded along the longitudinal axis on the refill, which cam pin engages an end of the refill. The cam pin has at least two locking positions, which are offset along the longitudinal axis. The writing implement includes a control arrangement having a resetting device, a freewheel couplable with an operating unit arranged at the operating side and a cam bushing couplable with the freewheel. The resetting device exerts a resetting force onto the operating unit. The freewheel is a rotatably supported body having a circumferential recess and forms an operative connection in a region with a second body that is rotatably supported and concentrically thereto. One of the first and second rotatably supported bodies is freely rotatable around its longitudinal axis in an angle range and transfers a rotation from the operating unit to the cam bushing outside of this range.

A writing instrument assembly has a writing instrument with a body and a working tip extended or extendable from the body. A holder has a landing spot for the writing instrument. The writing instrument is magnetically and detachably retained at the landing spot when attached to the holder. The working tip is sheathed or covered automatically when the writing instrument is attached to the holder and is unsheathed or uncovered when detached from the holder.

A writing instrument with a cap that lockingly engages a body portion via a locking assembly is presented herein. The locking assembly includes a pair of locking tabs on the cap that correspondingly fit within locking channels on the body of the writing instrument. With the tabs positioned within the locking channels, the cap is twisted or rotated such that the locking tabs slide past a node within the channels and restricts removal of the cap from the body portion.

A multi-purpose combination writing instrument is provided. The instrument can comprise a writing instrument holder, with 2 casing members connected together by a retractable unwinding tool. The retractable unwinding tool can be automatically retractable. One or more removable individual writing instruments can be reversibly attached to the writing instrument holder. An individual writing instrument is provided that comprises a male connector adapted to be mated to a corresponding female connector or that comprises an external screw thread. A casing member of a writing instrument holder is provided, comprising an automatic retracting mechanism stored in the casing member and adapted to be attached to a retractable unwinding tool and adapted to allow the retractable unwinding tool to automatically retract. Another multi-purpose combination writing instrument is provided, comprising a writing instrument holder that is fan-shaped (like a hand-held fan). Yet another multi-purpose combination writing instrument is provided, comprising a writing instrument holder comprising zero, one, or two casing members comprising a hinge assembly, which comprises a hinge.

A writing system comprises a writing tool comprising a barrel having a first end and a second end, a medium holder having a first end and a second end, the medium holder disposed within the barrel, wherein the medium holder is adapted to support a medium applicator to protrude from the first end of the barrel, and a magnetic core disposed within the barrel proximate to the first end of the barrel.
