Kevlar, what is this? Kevlar is polymer first produced by Du Pont in 1971. Kevlar can be made into strong, tough, stiff, high-melting fibres, five times stronger per weight than steel; it is used in radial tires, heat- or flame-resistant fabrics, bulletproof clothing, and fibre-reinforced composite materials for aircraft panels, boat hulls, golf-club shafts, and lightweight bicycles. It is also water resistant.

Because of school children being stab to death in Britian, now parents willing to pay hundred of dollar for this school uniform.

I wonder, knife can be purchase everywhere, if can stab into body, can stab the face, still will die. So should they invent something like scarf kevlar for covering the head?

Just wonder........
