Which property measures resistance to indentation or scratching?

Explanation:
Hardness is the property that measures resistance to localized plastic deformation, such as indentation or scratching. When a hard material is tested, the depth or size of the impression from an indenter indicates how resistant it is to being deformed at a small scale. Common hardness tests use indenters and measure either the indentation (Brinell, Vickers, Rockwell) or scratch resistance (Mohs scale). This is different from elasticity (reversible deformation), brittleness (tendency to fracture with little plastic deformation), and ductility (ability to deform substantially before breaking).
