The Rockwell scale measures the hardness of materials, particularly metals, using a standardized method that involves applying a specific load to an indenter and measuring the depth of penetration. Different Rockwell scales (e.g., A, B, C) are used for various materials, with the C scale commonly applied to harder materials like steel. The scale provides a straightforward numerical value that indicates hardness, where higher numbers correspond to harder materials. Thus, the hardness of a file, which is typically made from high-carbon steel, would be relatively high on the Rockwell scale, often around 60 HRC or more.

Active file: An active file is where you use a file quite frequently. Inactive file: A file that you use but not as frequently. Dead file: A dead file is where you don't use the file at all and is stored in your archives

Topaz has a hardness of 8 on the mohs scale.A steel file has a hardness of 6.5, or maybe 7+ if it has been hardened.In theory, the topaz is likely to be harder than the average steel file.=== === ...you may want to avoid putting this to the test, because, although you might scratch the steel file with the topaz, you might also just damage your topaz in the process, because, who knows, maybe your steel file is made of best high-carbon steel, which has a hardness of 8 on the mohs scale!And then there are steel files that have a layer of tungsten-carbide welded to the cutting surface. Tungsten-carbide has a mohs rating of 8.5 to 9! * For more information, see 'Related links' below this box.
The copper of the penny will rub off the file
Steel files are generally harder than common metal objects because they are made of high-carbon steel, which undergoes a heat treatment process to increase its hardness. This process involves heating the steel to high temperatures and then rapidly cooling it, making the file resistant to wear and able to maintain a sharp cutting edge.

A steel file can scratch minerals with a hardness of 6.5 or lower on the Mohs scale. This includes minerals such as gypsum, calcite, and fluorite.

Yes, a steel file can scratch muscovite because muscovite has a Mohs hardness of 2.5-3, while a steel file typically has a hardness of around 6.5. Harder materials can scratch softer materials according to the Mohs scale of mineral hardness.
The mineral that can scratch glass but can be scratched by a steel file is quartz. Quartz has a hardness of 7 on the Mohs scale, allowing it to scratch glass, which typically has a hardness of around 5.5. However, a steel file, which has a hardness of about 6.5 to 7, can scratch quartz.
