After reading that link, I simply had to go and do some searching of my own on the web to hunt down some information about my point. You see, the swords I have are authentic, and my numbers were guesses as I have never weighed them. (Can't just put 'em on my bathroom scale now can I?)
Anyway, it appears that we were both right to an extent. I learned something new today when I found out that swords have two weights, not just one. (Indeed I did need to study!) You see I have studied the arts of swordfighting and I have studied historical swords, but I have never studied the *science* of weaponry. Imagine my surprise that there is an "actual" weight AND what is called a "virtual" or "balanced" weight. The first is the weight as per, well, weight. The second is how heavy the weapons *feels* while it is being wielded. Seeing as my experience is hands-on and not scientific, I have been reporting the second weight!
I found a discussion somewhere where a professor had claimed some swords to be upwards of 25 pounds, and he got Hell for it. In an e-mail reply, this is what he had to say:

Anyway, as you can all see, there are not only disputes about actual weights, but two weights to begin with! I apologize for any confusion, as I have given the "virtual" or "balanced" weights. The longsword FEELS like 7 pounds in your hand, while it weights 2-5 pounds on a scale. Similarly, the katana weights 3-6 pounds but feels much MUCH lighter in the hand, which explains why the balance on these weapons is much better than conventional European weapons.
The reason I flipped out when I saw that link was because it reported rapiers in as heavier than longswords, which simply couldn't be the case! In fact it is true, the rapier simply feels a whole lot lighter in your hands. The longsword's weight is mostly in the blade. The rapier and katana both balance weight through the hilt, which increases balance. (That is the point I made about the longsword being slightly point-heavy, which means the weight is balanced too much on the blade itself.)
So it looks like we were both right. You were right about actual weight, mine are actual balanced weights. It does make me feel better, however, that a bonafide professor made the same mistake as I, heh. Nobody's perfect! Now I know about these two weights, though. That DOES, however, prove me right about the weights in the books being pretty close to reality, seeing as the books even state outright that not all encumbrance is weight, but rather how heavy it FEELS. This is why so many things weight so much more than actual real-world weight, because the books give the balanced weight.
That explains a whole lot, though.
