In a bit more nuanced version, researchers writing in the Royal Society of Open Science attached shark teeth to 12-inch bi-metal blade to simulate the head-shaking feeding behavior of large, predatory sharks. The scientists tested teeth from tiger, silky, sandbar, and sixgill sharks.
They recorded the results in terms of sharpness and durability. For example, the teeth from the tiger sharks proved to be the sharpest of all—but they dulled relatively quickly. The sixgill teeth cut more like a butter knife, but they also didn’t wear through repeated use.
"Some shark teeth are very sharp at the expense of quickly dulling, while others are less sharp but dull more slowly," the researchers wrote.
