The F series irons have two edges – one that rides on the side of your leather edge, and one that rides on the top of the leather. The iron heats the wax and paint on the leather’s edge, creating a smooth and even surface. It also creates a small decorative line on the top of the leather. The numbers correspond to the distance in millimeters between the two edges. Select sizes are also available in the FN variation.
