This is a handy multi-purpose lacing punch kit, which includes one handle and six different punches.
There are 3 single pronged punches in sizes ranging from 1.6mm to 3.2mm (1/16th to 1/8th of an inch) and 3 x 3 pronged punches in the same size range.
You can also use the smallest size punches as stitch punches, making this tool even more useful to have around!
