The "Pitch" is the center-to-center hole spacing in millimeters.
You can calculate the SPI(Stitches per inch) from Pitch this way.
SPI = 25.4 / Pitch
For example, as for 3 mm-pitch tool, it has 25.4 / 3 = 8.5 stitches per inch.

Comparison of stitch spacing



1. Make sure the tool is driven and pulled out in a vertical direction to leather.
2. Please work on a rubber pound board .
3. If the prong gets stuck deep in a rubber plate, make sure pull it out in a vertical direction. Do not shake or twist the handle from side to side, which will break the prong.

It is recommended to put the teeth in wax (e.g. sewing wax, beeswax) before using for thick or hard leather.
