Since I haven't found this information in wiki, I decided to post what I have found here.
Weapon - base damage.
Stone axe: 30
Metal axe: 45
Fyrdsman's sword: 70
Boar spear: 80
Bronze sword: 90
Hirdsman's sword: 125
Battleaxe of the Twelth Bay: not tested yet
Cutthroat knuckles: add constant amount of damage to all unarmed attacks (except kick - because it is leg) disregarding your ua, strength and base damage of the attack.
For q 18.4 19.5 19.4 damage was +6.
For q 32.3 37.0 37.9 damage was +9.
For q 39.9 47.5 48.1 damage was +10.
Seems to be 5 base damage multiplied by SQRT(Quality/10) and rounded down, where Quality is either substance, vitality or average quality. Need more testing though.
