What are the differences between emery cloth and sandpaper in terms of their abrasive properties and applications?

Emery cloth is typically more durable and has a finer grit than sandpaper, making it suitable for polishing and finishing metal surfaces. Sandpaper, on the other hand, comes in a variety of grits and is more versatile for different materials such as wood, metal, and plastic. Sandpaper is generally more affordable and widely available compared to emery cloth.
