In AD 60 Queen Boadicea led her tribe into battle against the Romans in Britain. She drove a chariot with sharp knives protruding from the wheels, to cause as much destruction as possible. A statue of her chariot can be found in London, England.
When operators drive unloaded forklifts with the forks up higher than necessary they are doing the same thing – except the knives are protruding from the front of their “chariot”. Those forks are as sharp as knives, hard as knives and can be fatal for any pedestrians in your path.
Remember forks should be as low to the ground as possible (but not dragging) and slightly tilted back.
