While it’s common for blade marketers to use some form of shark imagery or “SharkSaw” terminology in their otherwise metal-based products, we’ve been yet to see an actual saw blade that really is, in biological makeup, real shark teeth.

A team of biologists recently built the Jawzall modified power saw to investigate the cutting power of the teeth of different species of sharks…and what resulted is both terrifying and satisfies any sort of shark teeth-inspired biomimicry: using the natural motion of the power saw, the biologists were able to recreate how a Shark violently shakes their prey.

The research, which was presented recently at a meeting for the Society for Integrative and Comparative Biology, determined that shark teeth become dull very quickly, which is perhaps why Sharks rotate through so many new teeth. However, different species of sharks have equally different-shaped teeth, which result in varying degrees of cutting power.

“There actually is a significant effect of tooth morphology. That’s really striking,” said researcher Katherine Corn in a recent interview with Popular Science. “We may be able to extrapolate factors about feeding ecology from tooth morphology.”

While the Jawzall likely won’t be for sale at your local Home Depot any time soon, you can at least now know what it looks like when shark teeth are used as a saw blade.
