That is perfect thank you so much Tugadude!

I understand the difference in uses between the two, pricking irons and stitching chisels, but I don't understand from a manufacturing process what the difference between the two is. Can anyone shed light on this for me? Even though it is taboo, I have had success using a pricking iron to create holes and foregone using an awl. It seems that all pricking irons I have come across are french style (slanted flat teeth), could that be the difference and due to their thin nature they are more prone to break when hammered? Or could it just be a legacy tradition where manufactures couldn't make the teeth thin enough when the pricking irons were first made and therefore they had to only be used as a marking tool less the holes be too big?
