it doesn't make sense to stat AP and damage because the weapon damage is going up with new found /crafted/ bought weapons after you level up so a dagger lvl1 may have 5 to 10 but a lvl 10 dagger may have 40 to 60 HP
it's the same with weapon crafting:
doing a sword with lvl 1 char gets a smaller damage weapon than doing the same with a lvl 10 character with the same crafting skill
the crafting skill is only needed to check if you can make a sword, but not how powerful it becomes, that depends mainly on your character level!
