A five tooth thonging iron is a great starter tool for smaller leather goods. Pair this with a two tooth iron for curves and a ten tooth iron for medium to large projects.
These thonging irons are precision ground to perfection. They have a range of spacing options from 3.0mm to 4.5mm between each tooth.
Thonging irons create a horizontal hole that allows you to use leather lacing instead of thread. Their small punch size also enables you to use thread with these irons and create a straight stitch in a grooved channel.
Thonging irons are set with multiple teeth in a row, making it easier to produce beautiful straight lines of stitches. thonging irons can mark the leather deeper than a wheel and make it easier to follow up with your leather awl when sewing. Using a thonging iron also helps maintain the sharpness of your sewing awl since the irons are doing most of the work.
