Section 540

Today, a considerable number of white people in North America are descendants of Vikings.

…

There is no need to be too particular about the choice of axe handle.

As long as the material and hardness are good, it can do the job.

The eucalyptus in the camp is a good choice.

After being polished, the eucalyptus will be very comfortable to hold and feel great.

But because of the material problem, this kind of wood must take some effort in the process of polishing.

While talking.

Lu Yu squatted in front of the firewood pile and searched for a long time.

Finally found a piece of wood about 40 cm long, of moderate thickness and regular shape.

After peeling off the bark, the color and texture of the wood also met the requirements, and there were no hidden injuries such as insect bites.

And the axe handle was selected.

The next step is the old routine.

First, polish the axe handle.

Then pierce it with charcoal and put in the axe blade.

Finally, take a piece of rope and tie a few cross knots at the connection between the axe handle and the axe blade to fix it.

Soon.

An hour passed unknowingly.

After Lu Yu's meticulous crafting, a copper battle axe with a metallic luster was finally completed and appeared in front of the audience for the first time.

The copper axe blade is not comparable to the stone axe.

The unique metallic luster looks very tasteful.

The uneven surface.

It is even more artistically beautiful.

After all, it was made by hand.

This aura is definitely not comparable to the industrialized products of assembly line operation.

"Wait..."

"We still have to find a grindstone to polish the axe blade."

Looking at the "new weapon" in his hand, Lu Yu's mouth corners have been slightly raised.

It seems that he is very satisfied with this partner.

"The blade of a traditional Viking battle axe is very different from that of a common jungle axe. The biggest difference between the two lies in the way they are sharpened."

"Ordinary jungle axes, such as the Swedish Foss axe, are mostly flat-edged. Flat edge, or flat grinding, is the most commonly used method for sharpening blades, between concave grinding and convex grinding. It takes into account both sharpness and firmness. The longitudinal section of the blade is V-shaped, also known as V-shaped grinding."

"General outdoor hunting knives often use large flat grinding, which has both strong firmness and strong sharpness, and can meet the functions of chopping bones and skinning."

"But traditional Nordic hunting knives and axe blades are completely opposite to this. The Vikings have a very deep understanding of knives. After generations of inheritance, they have created a very special way of sharpening - Scandinavian sharpening."

Scandinavian sharpening, referred to as Scandinavian sharpening.

Sharpen from the middle of the blade to both sides.

This sharpening method can well retain the weight of the blade itself.

It is also very easy to use.

Skane blades are mostly used on traditional Nordic hunting knives, traditional battle axes and modern survival knives.

It is a very practical way to sharpen the blade.

It perfectly balances the strength and sharpness of the blade.

This is also one of the fundamental reasons why outdoor survival knives often use Skane blades.

No other reason.

It is because the blade is thick enough.

And the strength is good enough.

A Skane blade is enough for the survivor to cope with most of the chopping operations in the harsh natural environment.

In this regard, the flat-ground Damascus cannot compare with it.

After all, it is too thin.

…

Chatting.

Lu Yu turned and walked to the fire.

While introducing it to the audience.

While finding a small piece of charcoal from the embers of the fire.

Along the edge of the axe blade, a blade line with two sides equal and about five millimeters wide was drawn.

The purpose of the blade line is to facilitate grinding.

It can well avoid problems such as damaging the axe surface when grinding the axe blade.

"The Skane blade is double-edged. When drawing the blade line, it is best to consider both sides."

"If the blade is really biased, it will be troublesome."

"The combat effectiveness will at least drop by one level..."

A host who does not pay attention to details will definitely not be able to make a good program.

During the live broadcast, Lu Yu has always paid attention to details.

Whenever there is a key point, he will always say a few words.

Make the program richer and more three-dimensional.

Let the audience participate in it.

In fact, this way of explanation really adds a lot of points to this live broadcast.

The most important thing is that the audience also buys it.

While suddenly realizing, not only can you learn a lot of unknown survival knowledge.

For some principles, you also have a deeper understanding.

Soon.

After drawing the blade line.

Lu Yu stood up and came to the stone statue.

Stand in a horse stance.

Hold the blade with both hands.

Find an angle at random and grind it according to the area drawn by the blade line.

Single copper is relatively easy to polish.

Not long after, the double blades of the axe were roughly formed.

The entire blade is about five millimeters wide and looks very simple.

Next, we just need to continue to study the sharpness.

However, sharpening the blade is a technical job.

In addition to avoiding the edge from being off-center, it is also necessary to follow the principle of from coarse to fine.

In order to ensure the sharpness of the axe blade.

In short, there are many things to pay attention to.

It is also very troublesome.

Because the tools in hand are not up to standard.

The whole grinding process lasted for more than an hour.

During this period, Lu Yu even changed several stones of varying coarseness and fineness before he was completely done.

"Huh! It should be OK."

After he raised the axe blade and tested it with his fingertips, he let out a long breath.

"Okay, let's find something to test it and see how sharp it is..."

After saying that.

Lu Yu looked around.

Finally, his eyes were fixed on a tree not far away.

The next second.

Before the audience could react.

But Lu Yu had already taken a bow step, raised his hand, aimed at the tree trunk, and threw the battle axe out!

Whoosh!

The sound of breaking through the air was heard in an instant.

The Viking axe spun several times, drawing a beautiful arc in the air!

Finally, there was only a "bang".

When he looked again.

The sharp axe blade had already pierced into the tree trunk fiercely, more than half a pierce.
