User blog:Hulk10/Viking Weapon Weight

Shields weighed under 10 pounds, fairly light. Axes weighed around 4 or 5 pounds, also fairly light. Swords weighed around 2.4 pounds, quite light. Maces generally weighed 2.2 pounds. War Hammers generally weighed 2.4 pounds.

So the Viking weapons were not as heavy as some might think.

Although it is all relative.
