Bone folding tools are great for scoring and folding paper. Get clean folded edges every time. Also great for burnishing (rubbing). 

This bone folder is made from smooth durable plastic that will not damage paper. The length fits comfortably and provides precise control. The pointed tip is great for creasing and scoring paper, cutting clay, and getting into hard to reach corners. The wide end is ideal for smoothing scored crease or for burnishing a rub on.
