This may or may not have been addressed already, i dunno if it needs to be. But, i was looking the the apendix at the weight of some of these weapons and i thought maybe a warflail or 6 foot dopplehander would way more than 8 pounds. And a bastard sword i would think would way mroe than 3 pounds. But i don't have much experience with holding and using them, it just seemed kidna funny.
The weights in the appendix are accurate. Historical swords were no where near as heavy as many think they are.
For me info on this subject read this article:

EDIT: fixed link.
A handy place to go to get a feel of what items weigh and to get some excellent representation of what items really looked like, just go to this place...
