That CANNOT be right. I've got a rapier-like sword (ex ceremonial military, it's got a snakeskin hilt and an ornate handguard with the royal crest of George the Fifth in it), and even with the scabbard there's no way it weighs that much.
- Just checked, the kitchen scales say 1240g (2 and 3/4 pounds). WITH scabbard. Without, it's 830g. Now let's be fair and assume you have a belt to hang it off. Still no way in Hades.
Someone's dropped a decimal point somewhere.
