Definition
  1. Noun:
    • A grinding or sharpening tool: An "emery stone" is a manufactured abrasive tool, specifically a mixture of fine emery dust and a binding agent, which is formed into a solid block or wheel used for grinding, sharpening, or polishing metal and other hard materials.
Usage
  • An "emery stone" is used as a tool for abrasive tasks. It is typically applied to metalworking, tool maintenance, or craftwork to smooth, shape, or sharpen surfaces.
Examples
  • Noun:
    • The jeweler used a small emery stone to polish the edges of the silver setting.
    • For sharpening the old chisel, a coarse emery stone is more effective than a fine one.
Advanced Usage
  • Technical Context: In industrial or workshop settings, an "emery stone" may refer to a specific grade or shape of bonded abrasive, distinguished from natural sharpening stones.
    • The machinist selected a cylindrical emery stone for the internal grinding operation.
Variants and Related Words
  • Emery (noun): A very hard, granular mineral, a variety of corundum mixed with magnetite or hematite, used in its powdered form as an abrasive.

Notes on Meaning
  • The term "emery stone" specifically denotes a abrasive tool created by bonding emery particles. It is not a naturally occurring rock, though it contains the natural mineral emery. This distinguishes it from generic "grindstones" which can be made from other materials like sandstone.
