Why are "ancient" weapons more powerful than third age weapons?
In the movies/books, they always exclaim "oh, so and so is gonna kick but because he has the X, which is an ancient weapon crafted years ago so therefore it's awesome!" Seriously; the ancient elves, dwarves and Numenoreans (sp?) weapons seem to be the most revered and powerful. But, shouldn't ancient weapons be weaker than "modern" ones? I mean, if so, then why aren't we using swords crafted by the "ancient eyptians long ago"?
And, how come in all of the ages (several thousand years) the LOTR universe has never advanced technologically?
