A writing utensil adapted for promoting the development of a tripod writing grip includes an elongate body having a substantially polygonal cross section, and having three faces extending between a proximal end and a distal end thereof, and a boss member extending from an intermediate portion of the elongate body, the boss member being adapted for impeding a user's fingers from sliding along a longitudinal axis of the elongate body.

A device at properly aligns a user's hand when gripping a writing implement, such as pencil. The device includes four separate elements that combine in specific ways to grow and/or build a mature grasp. The device includes a base that is configure round the pencil and provides support for the user's fingers. A handle can releasably attach to the writing implement, providing support for the user's palm. A web support can be releasably attached to the handle, thereby stabilizing the user's thumb while gripping the writing implement. The device can also include an independent web positioner support that can be moved closer or towards the base depending on the separation needed. Advantageously, the grip device provides several stages to develop and build a mature grip pattern.

A mechanical pencil which is configured so that a rotatable cam is rotationally driven with an axis of the rotatable cam relative to a holder member stabled, and smooth operation of a rotational drive mechanism is ensured. The mechanical pencil includes a rotational drive mechanism for driving rotationally a rotatable cam according to writing pressure applied to a writing lead, and transfer rotational motion of the rotatable cam to the writing lead. The rotational drive mechanism includes a holder member supporting the rotatable cam so as to be rotatable, a first fixed cam formed with a funnel-shaped inclined surface Fu and a second fixed cam formed at an obtuse angle α relative to an axial direction. Cam faces of an upper cam and a lower cam alternately meshing with the first and second fixed cams are formed along a conical inclined surface Cs.

An apparatus and method to hold a tool is disclosed. In one embodiment, the tool holder comprises two elastic components. One elastic component fits around a finger and the second elastic component fits around the tool. In a more specific embodiment, the tool is a pen or pencil. A method is disclosed of attaching the device to a finger and a tool and using the device by moving the tool with one or more fingers that are adjacent to the finger with the attached tool.
