There is a bit about cam teeth in this article on the new Metolius cams: says they are designed so that "On soft rock, when the forces of a fall put enough energy into the cam to pull out, the rock actually pulverizes, creating a slick surface for the cam lobes to slide out of its placement. The goal of the shark fin profile is that it will enable the cam lobe to disperse the powdered rock to get down to solid rock."

These cams sound good but I do think we consume marketing. Some products claims are true, like this really is the "goal" of the shark fin above, some products like snack foods are constituted entirely of marketing. yum yum
