 Razer's weapon is a piercing arm which exerts approximately three tonnes of pressure per square inch (465 kg / cm2, 45.6 MPa) at its tip. The arm was designed to pierce opponents' armour plating and break their internal components, rendering them impaired or immobile. This weapon was inspired by the principle of the brake press — a piece of industrial machinery used to bend metal — and maximises damage through the use of hydraulics. The arm is also an integral element of Razer's winged self-righting mechanism, which rolls the robot back onto its wheels if inverted. In later series of Robot Wars, an interchangeable hook was attached to the arm to lift robots immune from being pierced. The popularity of crushing and piercing weaponry in robot combat events is attributed to Razer, which inspired many imitations.
