Or you can use one person and drain their blood over long time.

Let's do the math...

You can donate three times a year to the red cross (once every 112 days). According to some page, you donate around 10% of your blood volume each time.

That means, for a volume equivalent of 300 people, you'd need to donate 3000 times, which would take around 1000 years.

The vampire is going to need more people, or to keep a person alive 1000 years with vampire magic.

When you're harvesting the blood iron of your enemies you don't have time for ethics. A controlled study managed 4 weeks within ethical boundaries, maybe we can cut that in half unethically. So 14 days, 3000 . 14 = 115 years. So when you torture two people, you could manage to do 58 years. Better start early!

Orrrrrr capture the entire family of your foe and then you can name the sword something super cool about ending family lines

Maybe the sword is just the product of a small cult which drains blood to create it?

3 times a year? Where i live you cab give 1/2l every two weeks at a bloodbank.

And i can take more and by that activate a immune response to produce way more.

The same blood bank? You sure that's not plasma instead of blood? Plasma re-makes itself way faster than red blood cells.

Yeah twice a month blood, but only half a liter.

1

But remember they are your enemy so you could drain a bit more blood more often to shave a few years off maybe

2

You're off on blood production. "Safe" would be once every six to eight weeks for a pint. Plasma can be taken a lot more often. The red blood cells take a while to replenish.

But let's get real. You're not concerned about your enemy feeling well. Force them to take iron supplements and take a pint every other week. They'll likely stay alive that way. Fuck em, right?

2

But then you need to feed them iron-rich foods which could be used to make a vegan alternative instead, expanding your potential market.

These are the required elements for making steel:

  • Iron
  • Carbon
  • Manganese
  • Chromium
  • Phosphorus
  • Sulphur
  • Nickel
  • Molybdenum
  • Titanium
  • Copper
  • Boron

Source: https://www.cliftonsteel.com/education/11elementsfoundinsteel

So, iron is only step 1. Humans are carbon based lifeforms, so I'm guessing that carbon is also sorted, that's step 2.

There's plenty of other elements in the human body, like phosphorus and sulphur, but I'm guessing that it's going to take more than 300 adults.

This is extremely helpful, and fits perfectly into my secret plan

::: spoiler Secret plan I will use this info as background for a BBEG in my TTRPG game :::

Steel requires only iron and up to about 2% carbon

Rest are minor alloying elements used mainly in modern steel alloys to improve the steel beyond what just carbon steel could do like for example stainless steels

  1. Your link says these are elements commonly found in steel, not that they are all required. In fact it says of phosphorus and sulphur that they are generally undesirable.
  2. We don't need to make a steel sword, an iron sword could do.

Either way you would definitely need carbon, but as you say that's pretty easy. I don't think any of the other elements are absolutely required.

Those are all of them, but that's for a lot of different types of steels. You don't have to have all of those metals to make steel. You really just need iron and a tiny bit of carbon. A few of your ingredients help with purity, and the rest are additives for different steel properties you may want. Like a touch of nickel for stainless steel.

I searched for ingredients for making steel. I'm obviously not a metallurgist, nor do I pretend to be one on the internet :)

The meme triggered my interest into discovering just what might be involved.

Clearly I've just scratched the surface ..

This thread is giving me massive deja vu. I'm pretty sure I read almost this exact thing six months ago.

Beep boop are you a bot?

1

You only need iron and carbon the rest is already alloyed steel. You can definitely make a good blade out of only iron and carbon, it won't be stainless, it might be difficult to harden just right, but it will be flexible and hold a keen edge if forged right. The smiths of ole dealt with nastier steels containing all kinds of things making it worse, not better (such as excessive amounts of sulphur and phosphorus) so I'd say they'd manage.

3

Well, the non-metals and Manganese are way more available than iron anyway (probably molybdenum too). But it will be really difficult to create high-quality steel.

2

Listen. If they used surplus blood to do this (blood that was expired) and then held a raffle at the end of each year where all blood donors were entered to win a knife or sword made from the expired human blood iron, I bet they'd see blood donations skyrocket.

28

I think we should keep this color coded. Nigel Blue can do the copper sword made from the blood of 30000 horseshoe crabs.

After completing all these steps, the result was a little anticlimactic and disappointing. But still, I realized there was one thing left to do: taste it.

4

I want The Red Cross to hire you for marketing asap so this can actually happen.

6

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

lemmy.world

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

0

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.

You could also get a big sword-shaped ice cube mold, a chest freezer and probably not even a whole enemy.

You would have to do battle in freezing climates too though in order for it to remain physically effective

Though I imagine the psychological effectiveness might persist a bit longer

18

Mythbusters did this on their first episode: ice bullet. I think a sword might also be too brittle unfortunately.

lemmy.blahaj.zone

Listen there's definitely enough carbon in the body to boost that into a steel sword.

If we can make diamonds out of corpses, we can make steel.

Way too brittle if it was the weight of a typical sword, and way too heavy otherwise.

On the other hand, the cutting edge of that sword would be pretty amazing while it lasted.

8
lemmy.world

well what about just having the blade being diamond, like those diamond saws used for cutting rock.

2

Do you mean just the edge? Because with a sword basically the whole thing other than the handle is the blade.

But yeah, with a tiny diamond edge you'd probably have the best of both worlds, a light, flexible sword with an ultra-sharp cutting edge.

Still, the edge probably wouldn't last for long. If the diamond was attached to a steel blade and the blade flexed, the diamond couldn't flex and would probably snap.

3

Just toss your enemies into the recycler that extracts material for the replicator and replicate yourself a sword.

lemmy.world

So about 3150 pints of blood (10.5 being average for an adult).

Sounds doable XD

Edit: New ethical dilemma just dropped - kill 300 to forge the sword, or deny 3150 people blood in an emergency to forge the sword...

Here's the plan: we kill 330 people, save 330 people, the rest is free sword!

P.S. math may not be perfect

1

You know there’s a writer reading this meme somewhere: here; where ever it came from; where ever it will be reposted; and adding it to the story they are working on. Wonder where we’ll come across it first?

4

My very rough calculations using 85kg as an average adult weight, results in 153gr of iron

My problem is, that i dont have any expectations as to how heavy a longsword is but i'd assume it to be a lot heavier!

After further research it looks like the more appropriate number of humans needed to make an average longsword would be closer to 25.000

2

Males of average height have about 4 grams of iron in their body, females about 3.5 grams; children will usually have 3 grams or less

300 * 3g = 900g.

300 * 4,5g = 1350g

https://en.m.wikipedia.org/wiki/Longsword

and weighing approximately 1 to 1.5 kg

It's close enough, I'd say. OP's maths that is.
