randschaar

A randschaar is a hand tool used to trim or shear the outer edge of a material, typically in crafts such as woodworking, leatherworking, bookbinding, and light metalworking. It is a scissors‑like implement designed for flush trimming along a guide line or edge, producing a clean, square margin.

Most examples feature two blades in a scissor-like pivot, with long, narrow blades that may be straight or slightly curved to follow the contour of the work. Handles are usually wooden or metal, and the tool may have a screw pivot, adjustable tension, or replaceable blades. In woodworking, randscharen are used to trim veneer overhangs and to clean up edges where glue has seeped or fibers protrude. In leatherworking and bookbinding, similar tools are employed to trim excess material along edges to achieve a neat finish.

Use and technique typically involve aligning the blades with the edge or guide, applying steady pressure, and working along the edge to achieve a flush cut. The cut should be made with the grain or along a prepared edge, and care is taken to avoid gouging or nicking the surface. Maintaining sharp blades is important for clean, precise results.

Etymology and regional usage reflect its Dutch roots, with rand meaning edge and schaar meaning scissors. The exact design and terminology vary by craft tradition and region; in other languages, similar devices may be called edge shears or finishing shears.
