Assuming bronze age technology and the use of bronze for the blade, what is the longest blade / total length of sword that is possible and practical to use?
Bronze age Naue II swords were typically 70cm but I am wondering if a longer (1.2m +) sword is actually practical, both in terms of weight and strength of the material
Are there any technologies available today (or in a future sci fi setting) that could improve the possible sword length in a bronze material?
In the special magic world I am thinking of there is a special "repair" magic spell that can fix minor damage to swords in between bouts so this might aid durability
To answer comments:
John: total length, probably quite a lot of handle!
Erik: cutting slashing at a large opponent such as a 300kg Troll
