Functionally‐Graded Serrated Fangs Allow Spiders to Mechanically Cut Silk, Carbon and Kevlar Fibers (Adv. Sci. 44/2024)

Functionally-Graded Serrated Spider Fangs Hundreds of millions of years ago, spiders developed “functionally graded toothed blades” to efficiently cut tough materials like silk and artificial fibers such as Kevlar. Their serrated fangs focus pressure at the cutting point, making them more efficient than razor blades. This mechanism will inspire the development of advanced cutting tools.
