bonefolder

A bonefolder is a tool used in bookbinding, paper crafts, and other applications where a sharp crease or fold is needed. Traditionally, it was made from bone, hence the name, but modern bonefolders can also be crafted from plastic, wood, or Teflon. The tool typically has a smooth, flat edge with one or two pointed ends, allowing for precise folding and creasing.

The primary function of a bonefolder is to create clean, crisp folds in paper or other materials without damaging them. This is achieved by pressing down firmly along the desired fold line. The smooth surface of the bonefolder distributes pressure evenly, preventing tearing or smudging, especially when working with delicate papers or ink. In bookbinding, bonefolders are essential for folding signatures (the folded sheets that make up a book) and for smoothing down glued seams.

Beyond bookbinding, bonefolders are utilized in origami, card making, scrapbooking, and even in some sewing and upholstery applications. Their versatility lies in their ability to produce sharp, defined creases that enhance the aesthetic and structural integrity of the finished product. The pointed ends can also be used for scoring paper, making it easier to fold accurately. Different sizes and shapes of bonefolders are available, catering to various tasks and preferences within different craft disciplines.
