Weapons

 * Most 1 handed axes and broadswords weigh between 2 and 5 lb.

 * Flails are from 6 to 8 lb.

 * Knives are .5 to 1.5 lb.

 * Polarms range from 6 to 12 lb...not sure how much of that is blade.

 * Shortswords are 1 to 3 lb.

 * Spears range from 2 tto 5 lb.

 * 2 handed axes are 5 to 12 lb.

 * 2-handed swords are 5 to 10 lb.

Ah, nevermind.  Far too many parts.  If you have a weapon or armor, recording the weight is a great idea, for all sorts of reasons.
