Fake Extinction of All Mankind, and I Rebuild Civilization with my Bare Hands was Broadcast Live

Covering and burning the blade is the last step in making a knife.

It is also the key to a dogleg knife that is very suitable for combat standards!

Just do it right.

Will greatly increase the lethality of the knife!

The method is to put clay, iron filings, carbon powder and other materials.

According to the ratio of 1:1:1:1!

Blend in equal proportions to a sticky consistency.

Then cover it where the blade doesn't need high hardness!

It might sound a little complicated.

But in practice, it is very simple!

Don't be too late!

Set the blade aside.

Jiang Kui immediately found relevant materials.

High quality clay.

Crushed iron filings and the right amount of grass-wood ash!

Stir it together with water.

Then little by little.

Spread evenly on the knife body!

Because the soil has good plasticity.

No matter what kind of steel.

The covering effect is very good.

Just for a while.

The blade that was originally overflowing was covered with a thin layer of clay!

Only the blade is still exposed.

【Huh? What is this operation?】

【What kind of trouble do you make when such a beautiful pattern is smeared with mud?】

【Unknown to you!】

【Wood grass! Lord Kui is going to cover the soil and burn the blade?! 】

【What is the burning blade covered with soil? Is there a popular science emperor?】

【Blade covered with soil is a kind of local quenching technology, the purpose is to keep the blade area with high hardness, the blade body can still have good toughness! 】

【understood……】

[Good guy, Master Kui's knowledge is really too broad, I don't think there is anything he doesn't understand! 】

【As soon as you shoot, you are an old blacksmith!】

soon.

After applying the clay.

Charcoal fire in a rising flame kiln.

It has also been blessed to a specific temperature!

see.

Jiang Kui immediately used a fire stick.

Arrange the charcoal fire on the grate.

Then the knife embryo.

Sent in from the stove!

Insert into the red charcoal fire.

To ensure that the blade and blade are heated evenly!

"Hoohoo-hoo-!

Place the blade.

Jiang Kui picks up the lever of the blower again!

Pull the fan blade vigorously.

After the knife embryo is covered with soil, it is put into the furnace.

The temperature is just right!

at this time.

Plus the blower to support combustion!

It didn't take long.

The color of the blade embryo has changed significantly.

Extremely bright red.

At this point.

The blower can basically be stopped.

Next.

Burn for another seven or eight minutes at most.

It can be taken out.

The final quenching is in progress!

usually.

A razor-sharp blade forged from Damascus steel.

The metropolis will do the blade treatment!

But due to the particularity of steel.

The quenching step is also very particular.

About the final quenching.

With different media, the hardness obtained is also different!

Divided into water quenching, oil quenching and air quenching!

Water quenching means putting it directly into the water.

Fastest.

The obtained hardness is higher.

Oil quenching is to put it in oil.

Relatively slow.

The resulting hardness is relatively low.

Wind quenching is natural air drying.

slowest.

The resulting hardness will also be a notch lower.

Quenching of Damascus steel.

Generally, water quenching is still used.

Because this will not affect the hardness of the blade!

But just water is not enough!

It also needs to add a lot of tobacco food and grass ash!

If no carbon-rich material is added.

Directly into the water.

The carbon content of the blade will be lost to varying degrees.

serious.

It can even affect the final product.

"Huh, there shouldn't be much more..."

He leaned over and glanced into the furnace.

Observe the status of the blade embryo.

Jiang Kui whispered something.

Subsequently.

He immediately fetched the clay pot.

Fill it with water.

Added grass ash and other materials.

Stir well.

"Da Bai, get out of the way.

Drive away the curious Dabai.

Jiang Kui holds two wooden sticks.

Remove the charcoal from the grate.

Clip out the blade.

Then quickly put it into the crock pot!

"Fuck-!"

The red-hot blade cools quickly when it encounters water!

Outbursts of white air!

Because the temperature of the parts covered with mud will not drop instantly.

So the hardness will not be too high!

But the exposed edge part.

Quite the opposite!

After rapid cooling.

The hardness will become extremely high!

And then reach the highest state of the so-called "one knife, two worlds"!

Ten minutes passed.

When completely cool!

The blade that was taken out returned to its previous appearance again!

The pattern on the blade is very obvious!

Rustic carbon steel.

Tough and rough!

But the edge of the blade is as white as snow!

Shining brightly!

Even if not fully edged.

It is not comparable to ordinary swords!

It is not an exaggeration to call it a peerless blade.

I put the blade in my hand and looked at it for a while.

Jiang Kui took out the previous quartz slab again.

Sitting on the ground and grinding it up.

"Shhhhh-!

Nibble Scimitar.

ask for flowers

Also a typical double-edged knife.

It is different from the single blade of the willow leaf.

So it's not hard to grind.

Just follow the edge line and grind carefully.

There is almost no side edge!

soon!

Over an hour passed!

as the grinding progresses.

The edge is getting sharper!

then.

Jiang Kui has successively replaced three relatively delicate slates.

According to the mesh.

From high to low!

Gradually enrich the details of the cutting edge!

Soon.

After some polishing.

The blade that was originally shining brightly.

The appearance has changed greatly.

Sharper!

Just like a mirror!

Put your finger on it!

The sharp blade gives instant feedback!

No dullness at all!

"Dabai! Come here!"

Say hello to Dabai.

.0...

Jiang Kui tore off a wolf hair from its neck.

Carefully placed on the blade!

then.

Blow lightly!

"call--!""

next second!

Hair over the edge!

Divide in half now!

【Wood grass!!!】

【Blow your hair and break your hair?】

【It's too sharp!?】

[Flowing beer! What would it feel like if it was cut on the body, out of curiosity, let Dabai experience it for us! 】

【Boom!】

Eagle Sauce Audience:

【God! This knife is amazing!】

Dongying audience:

[Shocked! This is definitely a good knife! Master Yueshan's works can't break the hair in the air! 】

Colliers Audience:

【awesome!】

Immediately after.

Jiang Kui is in no hurry to be the hilt and scabbard!

Instead, he found a wooden stick the thickness of his forearm.

Dig a hole.

fixed.

Ready to use this stake.

Let's test the slashing effect!

Put the stakes away.

Jiang Kui stands with a knife!

A pair of cold eyes.

Aim for one third of the stake!

then.

The wrist is shaking right now!

Raise the knife and slash it!

"Whoosh!

The blade is broken.

Let out a groan!

next second!

Can't wait for the audience to react!

The original stake.

It's split in two!

Cutaway of the section.

No burrs and roughness at all!

It's as smooth as a saw!

【Wood grass!!!】

【Nima! It’s really a knife!!!】

【One-shot flow?】

【This is too sharp!!!】

(One more, ask for votes!) Righteousness.
