Single Line Creasing Tools
Single line creasers are used to make a single crease line parallel with an edge. They have one side longer than the other to ride over the edge of the leather. The other leg makes the crease line. The smaller the size number the closer the line is to the edge. They come in two size ranges. The regular single line creasers are narrower overall. Gomph made a larger size range they called "round edge creasers" and the Osbornes made a wider range they called "layer creasers". The tips on adjustable screw creasers can be opened or closed to set the width of the line. The larger sizes are called screw layer creasers or large screw creasers. Smaller ones are called loop checkering screw creasers or checkering creasers.
