In studying M Hunt's "English Fine Scroll" the geometry of the graver(air assisted) that pops the chip, many "things" influence the flexibility of the graver to pop the chip. Not only its shape but the material the graver is made off, carbide or HSS; the length of graver; slight hollow grinding of graver. For the beginner there are no personal preferences. What are some of these beginning point to develop personal preferences from? Length of graver relative to hand piece, material and basic shape of graver Carbide/HSS-Rd/Sq, hollow grinding, etc. Of course technique only develops with practice and is certainly a primary if not the primary ingredient in popp'in the chip.
