A mechanical pencil or pen that automatically extends its point or tip, or a system that marks a position automatically.
From auto- (self) + point (a sharp tip). This term originated with mechanical writing instruments in the early 20th century that featured automatic point advancement.
The autopoint pencil was a precursor to modern mechanical pencils, representing humanity's endless quest to never manually sharpen a pencil again—showing how innovation often starts with pure convenience.
