palette knife

This tool is distinct from a standard paintbrush in that it emphasizes texture and physical volume over blended gradients. It is primarily associated with the impasto technique, where paint is applied so thickly that it stands out from the surface, creating a three-dimensional effect.

In a professional studio context, the term refers specifically to the flexible blade used for manipulation. While it can be used for mixing, its primary artistic value lies in its ability to scrape, smear, and layer pigment in ways that brushes cannot achieve.
