A handheld device which is capable of writing on a variety of surfaces using ink or graphite, as well as a tool for scribing, scratching, and scoring numerous materials such as metal, wood, or plastic. The handheld device may be used for piercing holes in softer materials such as leather or paper, for breaking harder materials such as ice or glass, for self-defense against a human or animal attacker, to pry open or wedge closely positioned objects, and to clean or scrape material off of another surface. The handheld device resembles a common wooden pencil, making its purpose discreet to an outside observer. The handheld device includes a cap that covers the writing implement side of the device, which both protects the writing implement and also contributes to the overall appearance as a common wooden pencil.

Provided are an erasing implement and a writing implement equipped with the erasing implement, the erasing implement being capable of erasing writing regardless of the type of ink or lead of the writing implement, even writing with thermochromic ink or writing with pencil lead. The erasing implement is equipped with a first erasing member for erasing writing with thermochromic ink and a second erasing member for erasing writing of types other than thermochromic ink, and is configured by covering the outer surface of the second erasing member with the first erasing member.

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.

A stylus includes an elongate gripping member terminating at a writing tip, a communication interface housed within the elongate gripping member, a touch-sensitive retention clip extending from the elongate gripping member, and a controller housed within the elongate gripping member. The communication interface is configured to wirelessly communicate with a computing device. The controller is configured to detect a position or movement of a finger along a length of the touch-sensitive retention clip, and send to the computing device, via the communication interface, information based on the position or movement of the finger along the length of the touch-sensitive retention clip.

The Break-Proof Interchangeable Pen Clip is an innovative accessory designed to securely attach to writing instruments, preventing detachment and enhancing durability. The clip features a circular ring that fits around a high-quality metal screw, secured under a removable button casing at the pen's top. This design allows users to easily interchange and customize the clip's style or color. Made from robust alloy metal, the clip ensures a firm grip around the pen's body and can attach to various surfaces like shirt pockets, binders, and seat belts. The clip's arched surface design enhances its ability to remain securely fastened, minimizing the risk of accidental detachment. This invention combines functionality and aesthetic appeal, offering a reliable solution to maintain the integrity and utility of pen clips while providing opportunities for personalization.

The present invention provides tablets with interconnection features and a system of multiple tablet assemblies removably interconnected to one another. The tablets may be removably mounted to a vertical surface or positioned on a horizontal surface. Features of the present invention allow a user to remove or move one tablet from the system without disrupting or moving the other tablets.

A writing instrument includes a shaft barrel and a grip provided at part of the shaft barrel. The grip has a cylindrically shaped inside shaft part and a cylindrically shaped outside shaft part arranged at the outside of the inside shaft part, thinner than the inside shaft part, and made of a nonviscoelastic plastic. A space part is provided between the inside shaft part and the outside shaft part.

A structure for mounting a clip for a writing implement that includes (i) a pivotable clip which includes a stationary coupling portion extending along a reference axis; a main body that is pivotable in a pivot plane containing the reference axis, having two sidewalls each comprising a pivot-limiting hook; and a resiliently deformable curved portion connecting the main body to the coupling portion, enabling the main body to pivot relative to the coupling portion; (ii) a receiving member for receiving the coupling portion of the clip.
