The C.S. Osborne Space Marker tool makes prick marks in the leather so your stiches will be evenly spaced. The prick marks show you where to puncture the leather with your sewing awl. The higher the tool number, the closer the stitches are together. For example, a #5 has 5 stitches per inch. This quality leather tool has a hardwood handle and sharp prick points that are consistently spaced. C.S. Osborne has been making fine leather tools in USA since 1826.
