The samurai sword is his pride, a symbol of courage. The first samurai swords were made of hardened iron plates, shaped like a blade. But gradually steel replaced the iron swords. A real samurai sword combines the resilience of iron and the hardness of steel. However, experts say that the uniqueness of the Japanese sword lies not in the alloy of materials, but in the way it is made.
Instructions
Step 1
To craft a real samurai sword, purchase a strip of layered Damascus steel. Instead of Damascus steel, any other steel is suitable, belonging to the type of spring-spring or instrumental and always with a high carbon content. High-alloy steel is the best option.
Step 2
Use a large file to shape your steel strip into a diamond-shaped section, respecting all the traditional proportions of a Japanese sword. Saw the edge of the sword from the tip to the tip of the shank. Saw down the shoulders only after the final formation of the blade from beginning to end. Do not make the thickness of the cutting edge too thin. It must be at least 1 millimeter.
Step 3
Hone the surface of the blade with two files, one large and one smaller. Both files must be new. Move the file perpendicular to the axis of the sword, otherwise unevenness will appear on the surface. If you do not plan to put clay on top, then at the end, go over the blade with a file to add gloss.
Step 4
To perfect the line of the back, make a special device. Attach sandpaper to a twenty-centimeter wooden block. One side of the bar should be convex to match the deflection of the sword. With such a device, like a jointer, align the arch of the back.
Step 5
To heat-treat your sword, you will need a large muffle furnace with a one-meter deep chamber. Submerge your sword almost horizontally in the oven with the blade down. The same procedure can be done in a forge using coke. Be sure to carry out annealing in a layer of ash. To do this, make a narrow pencil case along the entire length of the strip and heat it until it shines orange. Soak the sword in a hot construction for two hours, then judge.
Step 6
Once it has cooled down completely, proceed to the final sanding step. Use industrial abrasives to slowly back and forth the bar along the sword to make it look like a Japanese samurai sword.
