nadcinienie

Nadcinienie is a Polish term referring to a shallow notch or nick made along the edge of a material by applying a small, controlled cut. The purpose of nadcinienie is to create a starting point for a break, to relieve stress in a line, or to facilitate the fitting of components. The word derives from the verb nadciąć, meaning to cut into or notch beyond the surface, with the -enie suffix forming a noun.

The concept is used in several crafts and technical disciplines where precise edge work is important. In woodworking and metalworking, nadcinienie can mark or begin a line for subsequent breaking, bending, or joining. In sheet metal and plastics work, a notch may serve as a relief point to improve folding or to guide a later cut. The notch is typically shallow, limited to a small fraction of the material’s thickness, and is intended to minimize tearing or distortion beyond the notch.

Practically, nadcinienie is performed with a sharp utility knife, a fine chisel, or a specialized scoring tool, aligned along the intended line. The edge is usually scored or lightly cut, after which the material can be snapped, bent, or continued with downstream operations. Care is taken to avoid excessive depth, which can compromise structural integrity or create burrs that require smoothing.

Nadcinienie is distinct from broader cutting terms and may be closely related to concepts such as scoring and notching in various trades. See also notching, scoring, and edge prep.
