Thonging Iron One Tooth (mm)


In stock

SKU: dd-st01 Categories: , Brand:


Our one tooth thonging iron allows you to make single stitch marks, which is especially useful when creating stitches at corners where the larger irons don’t end exactly at the corner. You can also use a single tooth iron when you need to make a small line of stitches that need to be custom spaced to fit with the design of your piece. This one tooth iron matches with our other mm-based thonging irons.

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.
