Original sentence: For such reasons, this concept has been rejected by the scientific community.However, teeth are not metal blades, they are made of unsupported enamel, and would have been easily broken against hard material such as bone.It has also been argued that the mandible would have been an impediment to effective stabbing.It was once suggested that the teeth of saber-toothed cats were used in the manner of a hand wielding a knife.This idea describes the use of the canines for stabbing: the machairodont would grapple with an animal, open its mouth, retract from the animal, and swing its head down with enough force to puncture the animal's skin and flesh
