ok, but humans also regenerate blood, very slowly but it does happen. So theoretically, you could contract your family members to draw blood to be used to make a longsword out of your family's bloodline. And have it become an heirloom.

imagine, over the centuries of blood donation, the sword slowly grows from a knife, into an absolutely huge dragonslayer behemoth

Is it slowly? I thought you replaced all the blood from a blood donation within a day or two

i don't think it's a day or two, the recommended regulation is i think a certain amount once per month? or so. You'd have to google it.

I think the body recovers from losing blood in about a day, but it doesn't replenish it.
