undercuts

Undercuts is a term used in several fields to describe a feature cut or recessed beneath a surface, or a pricing practice that undercuts competitors. The exact meaning depends on context.

In economics and retail, undercutting means offering goods or services at a lower price than rivals to gain market share. It can trigger price competition and, when aggressive, raise concerns about predatory pricing or unfair trade practices.

In manufacturing and design, undercuts are recesses or grooves that lie beneath a surface. They complicate mold release and may require special tooling or draft angles, but can improve retention or fit in assemblies.

In dentistry, an undercut is a deviation in tooth structure or restoration that creates a negative space under an edge. It affects impressions, retainers, and crown fits, so clinicians manage undercuts during preparation and restoration.

In hairstyling, an undercut is a cut where the sides and/or back are shaved or clipped short while the top remains longer. Variants range from subtle to bold, often paired with fades or disconnects.

In other contexts, undercuts describe similar recessed features in woodworking, metalworking, or engineering, and the general idea is a recessed area that alters how parts join, release, or retain each other.
