Hello mr thejapanese sword, which the clay is used in temper? Some special?

Tks.

[TheJapaneseSword]

Yes, It is basically a clay slurry mixed with grains of polishing stone and charcoal dust etc. It is a different mix depending on the swordsmith. Many have their own additional secret ingredient, or ways of mixing etc.

Whats the Gray paste that he applies on the blade for and why does he heat the sword again?

[TheJapaneseSword]

It is an application of clay to control the cooling different rates required of the back and the cutting edge. This causes the steel of the cutting edge to become very hard, so that it can take a razor edge, whilst the back retains some flexibility to absorb the shock of impact when cutting.

@TheJapaneseSword doesn't it also cause the hamon to later appear during the polishing and sharpening process?

[TheJapaneseSword]

@999tyman Yes, it is this clay application as a part of the quenching process that creates, as well as determining the shape of the hamon. Then the beauty of the hamon is then revealed by the lengthy polishing process using up to 20 different grades of stones.

a real blade forged in the traditional way is priceless, the money is to make sure that the swordsmith would be in good health and has abundant provisions to continue his work, these are real weapons, used by soldiers and worrier in real battles, the state and the well-being of the sword IS the life of the worrier who wields it, they didnt 'pay' for the sword, the sword is priceless because it almost always determines if they will live through the next battle.

The pattern creates alternating hard and soft steel creating greater elastic modulus to help dissipate force from the hard cutting edge to the softer body. Keeps the blade from breaking when force is applied.

btw the layering process creates the same force transfer principles as in the Composite bow

I wished he can make a sword for me. If it's not asking too much.

@FRANC1300 your also paying for a premium

[llew777]

This is an instrument that you cannot buy at Walmart, and good on for that, high quality and tradition,pride in workmanship, Quality lives, This making of this instrument is the highest of quality art work

Thank you for this, Rob From Canada

[killa2dacore]

This is how you make a sword, by long and precise work , not by mass prudising something, like most sword and knifes companies have tryed to do. I still say that any come close to an original japanese katana.

[joja198]

Thanks for this videos very good

[xZatoichix]

i love the way he applied the clay, the hamon looks awesome

[ZdenekJindra]

@FRANC1300 Katanas are being made all over the world. €500 will likely buy a very nice katana with genuine hamon made in USA or Europe. But forget about a true Japanese one, those start at €10000. You are basically paying for no shortcuts being taken in the manufacturing process: Self-made furnace instead of using industrial rods, manual hammering instead of machine hammering, manual grinding instead of a belt sander, natural quartz stones instead of corundum compounds, hand-carved fittings.

how to know what sword is original,from ppl who made them,or high price,or some certificate?i want to buy me one ,and i am afraid to buy cause maybe its some cheap thing.i saw in store they sell all kind of knifes and swords,and i like katana,so if i buy like 500 euros i dont want to throw the money on crap

[TytusTolshemLives]

@jimmyjamesWang What are they so worried about?

[attackoftherandom]

i thought you put the clay everywhere exept the edge so only the edge is hardened. wich is it?
