HOW SAMURAI BLADE WAS MADE

Samurai sword was invented in the 16^th century and was originally made in Kyoto, Japan by a very skilled and experienced Japanese blacksmith named Uchiha Nazaki. It was originally thicker and heavier compared to the modern samurai. It was a very deadly weapon that the extremely sharp blade can easily chop a human body into puzzle pieces. This sword had been used by ancient Japanese warriors and was even used in the World War II.

The samurai is first made by sandwiching together a chunk of high-carbon steel with a chunk of slightly softer high-carbon steel. The steel pieces are then hammered together and folded over onto each other continuously until only one slab of steel emerges.

This steel is then heated in a constant hot temperature, pounded,

then heated again, and pounded again until the steel becomes long and thin. The interesting part about this repetitive process is that the bonding of hard thousands and creates a laminated sandwich effect of thousands and sometimes millions of layers. This strengthens the blade while keeping it soft enough so that it won’t break on impact. If the sword is too hard, the sword becomes brittle and can break when clashing with other swords. If the sword is too soft, the sword will not hold a sharp edge for very long. It will dull rapidly, and that could mean death on the battlefield. The balance has to be just right.

Once the desired shape was made after this repetitive process, the blacksmith covers the back dull edge of the blade with clay while leaving the cutting edge exposed. The coated blade is then heated up for a short period of time and is then instantly cooled in water. Then the clay is peeled off, and what remains is an edge that is hard enough to hold a sharp edge but also soft enough to resist direct impact.

The bare blade is then sharpened on a wet stone by hand (it is forbidden to sharpen a samurai sword on grind wheels) and is cleaned with water or sometimes chrysanthemum oil.

That was a detailed process and steps on how samurai blade was made. The samurai blade is extremely sharp and must be handled carefully.
