Diamond Lapping Compound

Diamond paste is a type of polishing compound made from finely ground or powdered diamond particles, and some kind of liquid, usually water based. Diamond powder itself is simply paste without the water or other liquid binding agent. It may come in a syringe for more exact application, or even come in a small pump-spray bottle. Some manufacturers produce pastes with different sized grits in specific colors. Color coding can facilitate selecting the proper size of grit for the surface that is to be polished.
This compound can be used to polish or sharpen a variety of tools and surfaces. Diamondpaste is recommended for finely polishing various metals, including metal blades and other metal surfaces. In the case of a metal blade, of course, the paste not only polishes the flat surface of the blade, but also finely sharpens the cutting surface. Diamond paste is appropriate for use on ceramic, glass, and mineral surfaces. It can also be used to clean surfaces made out of the aforementioned materials.
