How did the jian and dao develope thru ages? What material, form of blade, pomel and forging technic were used thru time? Is there a book or page wich has like a timeline of develoment? I need this information because i want to make 1:1 scale wooden models (if someone has some technical drawing, blueprints with messurment or anything that can help me pleas post)

Have a look at Thomas Chen's website, which is probably the most useful online reference on historical Chinese swords: http://thomaschen.freewebspace.com/index.html

Chinese sword chronology timeline:
