The spring-operated emergency blade has an additional security lock to prevent self-injury. The marlin spike on the back side of the has a rough surface for greater ease of opening and a dedicated lock holds it open. The glass-breaker at the end of the handle is effective on glass and plastic surfaces. The knife also comes with:
