Damage in weapon tooltip doesn't have meaningful value.
Test - damage vs opponent without armor (1000 str), cleave at 99 blue opening.
Bronze sword: 698
Hirdsman: 779
Hirdsman sword QL: 150, damage: 445

Bronze sword QL: 245, damage: 445

They look similar, but.. bronze sword deal way less dmg because of damage formula:

It's way better to use hirdsman even tho damage in tooltip is equal to bronze sword.
