Pricking Wheels are used to mark stitches along a curved line or where using a pricking iron is impractical. They are also a great compliment to pricking irons which produce straight lines. Pricking wheels can be used instead of the 2 tooth iron, especially where there is a very long and gradual curve. The Doldokki pricking wheels are not like the normal overstitch wheels that you often see. Each tooth is very sharp and creates a diagonal line instead of a point.
Pricking wheels are usually used just to make impressions for stitches, but they will also create marks that go all the way through on softer or thinner leather. The pricking wheels themselves are also interchangeable, so you can swap out new or different sized wheels to suit your needs.
