Fun Fact:

The Gladius, the short sword that became the signature weapon of the Roman legions, was designed for stabbing and thrusting and only weighed between 25 and 32 ounces—only 1.56 to 2 pounds! That's less than most laptops! Even my lovely new machine (a Macbook Air, which is absurdly light) weighs 2.96 lbs, almost a full pound more than a Roman legionary's sword.
