Viistetty

Viistetty is a Finnish adjective meaning beveled or slanted. It describes a surface, edge, or cut that forms an angle with an adjacent face rather than being square (perpendicular) or flush. The word derives from the verb viistää (to bevel, to slope) and the noun viisti (bevel, diagonal).

In practical use, viistetty is common in woodworking, metalworking, architecture, and design. A viistetty reuna refers to a beveled edge; viistetyt kulmat describe bevelled or mitered angles used to join materials at corners, such as in picture-frame corners or window casings. Bevels can serve functional purposes—such as easing assembly, protecting edges, or aiding drainage—and aesthetic purposes, such as creating softer lines or influencing how light interacts with a surface.

Bevel angles are specified in technical drawings and manufacturing standards. A common phrasing might indicate a viiste of a certain degree, for example a 45-degree bevel. The term is used across disciplines to indicate that a surface or edge has been machined or finished at an angle rather than square to the reference plane.

See also: bevel, miter joint, beveling. In Finnish technical terminology, viistetty is frequently seen in carpentry, metal fabrication, glass work, and construction contexts to describe non-square edge finishes.
