Can a knife pierce human skull?

While knives are sharp and can cause severe injuries, penetrating a human skull is exceptionally difficult due to the skull's rigid and thick nature. The hardness and density of the human skull act as a protective barrier, making it highly challenging for most knives to penetrate.

Additionally, the skull's interior is filled with the brain's soft tissues, blood vessels, and cerebrospinal fluid. Piercing through these layers could result in substantial damage and life-threatening injuries. For a knife to penetrate the human skull, it must overcome significant force and resistance.

Therefore, it's important to understand that while knives are dangerous and can inflict serious wounds, they typically cannot pierce the human skull unless exceptional force or specific circumstances are involved.
