A thin metal stylus was employed as the drawing tool for impressing the scaled down profile image onto the paper (see figure 3 on the pantograph). The artist would then use this imprint as their guideline to work from, and could easily modify the profile as they saw fit whilst cutting it out from the center of the paper.
