A stylus is a pointed hand-held instrument used to apply marks to a surface — paper, drawing tablet, or capacitive screen — with greater precision and control than a finger allows. Its defining parameters are: (1) a pointed or fine-tipped working end, either abrasive (graphite, polymer nib) or conductive (rubber disc, charged capacitor), (2) a grip shaped and balanced for sustained hand holding, and (3) a target surface that registers pressure or conductivity through the tip. It persists through physical fabrication from durable materials (wood, metal, plastic, rubber) and through the cultural transmission of its form across generations of scribes, artists, and interface designers.

Definition
Why it is in scope
A human-made pointed instrument designed for writing, drawing, or interacting with touch-sensitive surfaces. It is a tool that extends the human hand's capacity to apply precise pressure and control to a surface, manufactured from materials such as wood, metal, plastic, or rubber, and persisted through physical fabrication and material culture.
