Emi Yagyu nodded and introduced, "The Ami clan is a family that has been appraising, grinding, and wiping swords for generations. It has been passed down from generation to generation, originating from the Suga family stream, and the family crest is Xingmei. ”

Legend has it that his ancestors also inherited the art of swordsmanship in his early years, but since then, he has become known as the first calligrapher of Kanei no Sanbi, and he is also a versatile artist who has also dabbled in pottery, lacquer art, publishing, and tea ceremonies. ”

"All the famous knives of our Yanagi family are sharpened and cared for by them, which costs at least tens of millions of dollars a year, and I have visited many times in the hope of learning the overall grinding skills, and the results are ......."

After speaking, he shook his head, Su Yuan looked at the regretful expression on the little girl's face, and said with a smile: "If you meet me earlier, why worry about this little thing?"

After speaking, he picked up the stone and said, "Isn't it just the overall grinding, you look at it!"

Emi Yanagi looked shocked, stared at Su Yuan in disbelief, and saw him pick up a piece of Iyoto from Matsuyama, Ehime Prefecture, and start the first job, going to the ground.

Generally referred to as Arato, about 400 mesh, the texture is relatively hard, the cutting ability is good, and it can remove all kinds of hard rust on the surface and make a large shaping of the tool.

Su Yuan quickly finished finishing the surface with the wasteland, and then replaced it with a water preparation. Produced in the Amakusa area of Kumamoto Prefecture, the mesh count is still about 400 mesh, but the hardness is not very high, and it is good to clean up the traces left by the previous barren stone, and at the same time to repair the knife shape and large defects.

Produced in Yamagata Prefecture, the 600-mesh corrected tome has a relatively hard texture, and the blade embryo is ground into a preliminary blade and pickaxe, and the prototype of the knife's personal style begins to appear.

Emi Yanagi stared intently at every move, and realized that once the knife was developed into a blade, it meant that the grinding process of the big action was about to end, and after that, it would be more meticulous grinding, and basically began to enter the realm of artistic creation.

Su Yuan cleaned the knife embryo again and chose two stones, the middle name warehouse, which is about 800-1200 mesh, and the thin name warehouse, which is 1500-2000 mesh.

The texture of the two kinds of stone is harder, and the function is to divide the ground muscle and blade of the knife more clearly, but the effect is different, depending on the object and the effect of the need to use separately.

The reason why the price of natural stone is several times that of artificial stone is that the difference lies in the softness and delicacy, even if the number of meshes is the same, because natural stone contains some special chemical components, the color of the knife will also change slightly, which is more beautiful.

"It's time to start cutting and leading!"

Megumi Yanagi couldn't help but blurt out, the most critical moment is coming, and the ground and blade on the knife need to be drawn out with a special technique. Su Yuan picked up a piece of inner cupoon, as high as 4000-6000 meshes, produced in Kyoto's Ohirayama.

The changes in the blade and the earth muscles are fully reflected. This is a very important step, and it is a great example of the skill of the grinder.

During the whole process, Su Yuan was engrossed in the details of grinding, although there was a sharp blade, but the grinding ancient method could be passed down for thousands of years, and there must be something outstanding, wouldn't the combination of strong and strong have a better effect?

Clean the knife embryo again, check it again, and explain: "After completing the first step, the following is Shi Shangyan, which can be regarded as the grinder's understanding and re-creation process of the knife itself, with a strong artistic creation and aesthetic judgment component. ”

As he did it, he explained: "First use the earth to further process the knife to better reflect and enrich the muscles of the earth, such as the small changes such as the stick ying. ”

"The blade to be used below, before using another kind of stone, carefully grind the green stone into the desired shape and then use ......"

"Both Diyan and Blade Yan should be ground into very fine flakes, gently pressed with the tip of the fingers, and then ground little by little according to the direction of the ground and blade on the knife, and experience the ...... with your heart."

After completing the second step, Su Yuan stood up and began to mix the secret recipe, and Emi Yanagi was even more excited, and introduced to Xu Kui: "The grinder will mix the powder and liquid into a paste in a certain proportion, and then use Yoshino paper to dip it in the ground muscles to treat it. After this process, the changes on the ground will become clearer and more powerful, and the color will be more beautiful, which is the legendary wipe!"

Su Yuan smiled and said nothing, there are great differences in the recipes of different grinders, and the materials used by Ben Ami are powder, some iron powders, clove oil, and powders and oils of other materials.

Different works, the same grinder uses different recipes, and the results after treatment are also different. The recipe is the grinder's biggest secret.

"In my opinion, the first three steps are not difficult, but the most interesting thing is to take the knife!"

Su Yuan picked up his inner wisdom again and analyzed: "The key to this step is not the technique, but the grinder's understanding of the knife-making school, the knife author and the knife itself, as well as his personal aesthetic ability. ”

"According to the understanding, to strengthen, weaken, add and delete some strokes, so that this knife finally becomes a perfect work. The whole process is like creating an ink painting, and there is a lot of room for creativity. ”

"I remember that your family had a short knife made in the second year of the Yuan Turtle, and the first grinder of the knife, although the earth muscles were very strong, the blade was obviously a failure. The blade script is very stereotyped, almost unchanged, boiling and squeezing are not represented. ”

"But the most serious thing is that he changed the original blade of the knife, and there was also a blade on the side of the building. This kind of burning method is called Dong burning, which is a relatively rare burning method in ancient knives, but he is completely unaware of this problem, not only did he not take it out, but also made it into the ground muscle. ”

Su Yuan put down the stone and said disdainfully: "It's just a violent thing!"

"Knives also have a lifespan, and every time they are sharpened, they will be one point older, because the blade will be thin and less, and it will inevitably be scrapped when sharpened to a certain extent. ”

"So the knife will also die!"

Xu Kui and Yanagi Emi have solemn faces, they are all masters, grinding to this extent, it is far from enough to rely on eyes and hand feeling, a good grinder must also use all other senses to distinguish the difference in grinding degree between the stone and the knife.

With the senses of hearing, sight and touch, you can judge the current grinding progress and decide what to do next and how to do it.

Su Yuan put down the stone and opened the toolbox, which contained steel tools of different shapes. The fifth stage of rod research began, and the pickaxe ground and building were treated like mirror polishing.

The katana is aesthetically exquisite, and the sword is divided into three colors, that is, the pickaxe, ground muscle, and blade of the sword are processed into three distinct areas. After the blade is done, a mirror-like effect is made in a specific direction according to different parts.

The final step is the makeup study. The first cut floor and the filter on the stem are processed, and finally the grinding mark unique to each grinder is applied at the junction of the blade and the stem.

Once this process is complete, it means that the grinder considers the piece finished and leaves his own unique sense on the piece.
