Yeah, once they changed their idea. :p Lucas wanted them to appear to be heavy at first and Luke always had to hold it with two hands. (just in fight scenes, maybe?) But then the first time he ever touched one, he's swinging it around with one hand. Hmm...
Padme also made a bit of double entendre about Anakin's being heavier than she thought it would in the Clone Wars series (presumably the hilt).
Maybe it's like a lawn mower, the Sabre may be light but the vibration from the energy gives it an impression of weight over time, that and the weight of the hilt could make it difficult for an inexperienced user or a quadruple amputee to whirl around.
