scratch awl
Definition
Noun: A scratch awl is a hand tool featuring a sharp, pointed metal tip (or awl) set into a handle. Its primary function is to scribe or mark precise lines, points, or patterns onto materials like wood or metal to guide subsequent cutting, drilling, or assembly.
Usage
The scratch awl is used to create visible, fine scratches or indentations on a workpiece's surface. This marked line serves as a guide for a saw, chisel, or other cutting tool to follow. * Before cutting the board, use a scratch awl to scribe the line. * The carpenter marked the drill points on the metal bracket with a scratch awl.
Advanced Usage
