Double-Line Creasers

Double-Line Creasers make two parallel lines (a "bead line") parallel with an edge. They have one leg that is longer and rides over the edge of the leather. The two shorter raised lines will make the beadline. Some people use these to mark out a stitching line and have a bead next to it.
