Tip 1: How to make a katana

aura that surrounds the legendary samurai sword - katana, maintains interest and admiration for these weapons for no one hundred years.Katana - strong, light and flexible sword.He becomes so due to special materials of which it is forged, forging and special equipment, according to legend, the correct mental attitude of the master.
you need
  • ferrous sand
  • Foundry
  • Horn
  • Hammer
  • Anvil
  • Charcoal
  • Rice straw
  • Clay
  • powder sandstone
  • Water
  • tools for grinding and polishingsteel
Guide
1
To forge katana correct, you need to stock up special "black sand" from the Japanese coast.It ferruginous sand from which you will smelt tamahagane - traditional Japanese steel used for forging samurai swords.
2
Load ore sand foundry - the Tatars - and smelted on charcoal about 4 kg of steel.The temperature in the melting furnace should be up to 1 500 degrees Celsius.
3
Sort the steel at low carbon and high-carbon.High-tamahagane heavier, bright silver.Mild - rough, gray-black color.
4
Cover the bottom of the forge crushed charcoal, add large chunks of coal and ignite them.Place a layer of mild steel and then pour a layer of charcoal.Wait for steel sink to the bottom of the hearth.
5
Cover the bottom of the hearth ash from rice straw mixed with powdered charcoal, put a layer of high-carbon steel slide, pour on top of the charcoal.Begin vigorously pumping the bellows.Wait until the forge will not only steel.
6
Take tamahagane pieces and begin to forge one flat sheets half a centimeter thick.Cool sheets in water and breaks down into the plate area of ​​2 square centimeters.Sort the high-carbon steel and low-carbon on.
7
Take the selected pieces of high-carbon steel, lay on a steel plate with a handle.Wrap the paper and obmazhte clay.Place in a forge.Fill with charcoal, and heat for at least thirty minutes to a bright yellow or white.
8
Remove the block from the forge, anvil, and place face down on a rock.Again, place in a forge, heat and proc.Repeat this cycle several times.
9
When your bar is ready, do it nadkoly bit and take over.Again the heat and process a hammer, until the upper and lower half is not an alloy block and not return to the original length.Repeat this cycle six times.
10
before continuing forging bar cut into four equal parts.Put them on one another and weld them together by heating and forging.More repeat six times folding, heating and forging.You now have a steel "kavagane."
11
Take pending low-carbon steel, forge of her bar and then fold it and re- forge another ten times.You get the "singane" or steel core.
12
forge kavagane of a flat plate of 40 centimeters in length, roll in the form of the letter U. The inside of the plate, place the bar singane.Heat the workpiece in a forge to bright yellow and start to constrain.Reach full welding plates together.
13
Make workpiece blade, warming bar in mining and forging of a rectangular piece.

Give blade shape by stretching the workpiece perpendicular to the length.Form the cutting edge, the edge, side edges and butt.
14
With a knife-scraper treat the surface of the sword.Files treat butt and a cutting edge.With stone, carborundum, do the preliminary grinding of all blades.
15
Cook sticky clay mixture of clay, charcoal and crushed sandstone powder in equal proportions.Dilute with water and trowel, apply to the cutting edge.A thick layer along the butt and on the sides and a very thin layer along the edge.Wait until the clay hardens.

Heat the blade in the furnace to 700 degrees Celsius, and cool in the water tank.
16
Correct bending blade and polish it.
17
Files treat shank blades.
18
End production of katana, making the handle of the two halves of the timber wrapped in skin first, and then a cotton cord.

Tip 2: How to make Bulat

Bulat- is steel, which is due to the unique technology of its manufacture is of particular surface structure, providing increased flexibility and hardness.Since ancient times, the material used for the manufacture of cold steel of high quality, such as the combination of hardness, elasticity, ability to keep sharpened condition, no ductility and advanced materials.
How to make Bulat
Guide
1
According to chemical parameters damask differs from ordinary steel high carbon content in its composition, but on the physical characteristics Bulat keeps figures ductility, typical of a low-carbon steel, and afterhardening of metal is becoming even harder than the low-carbon metal, due to the internal structure of Damascus steel.In appearance wootz always be distinguished due to the presence on the surface of the chaotic pattern that is formed by crystallization.
2
There are many ways to create a Damascus steel, both modern and traditional.Today Bulat melted.Load the steelmaking furnace components Damascus steel: a steel with low carbon content, or iron, which melts at temperatures of about 1650 degrees.Thereafter, the molten metal fill silicon and aluminum, and only then - graphite.Thus in the furnace is formed of synthetic iron, wherein the carbon content will be about 3 percent.
3
Further molten iron fill small chips of soft iron or steel with low carbon content.This chips or small pieces of metal should be dry and clean, without any signs of oxidation on the surface.Write chips need to gradually overall its mass must be from 50 to 70 weight percent of iron in the furnace.
4
When melting metal chips becomes like mush, so with every new introduction of pieces of metal furnace should be heated.After making the total volume of metal shavings is heated again, but only to a state in which it maintains a heterogeneous structure.
5
Thereafter, the damask steel pour in the form of graphite or leave in the oven for curing.In the first case, a damask ferritic layers and low carbon (0.05%), while the second - wootz layers with carbon and high carbon content (1%).
Helpful Hint
learn the art of making traditional katana can be extremely personally present masters.There are many subtleties and secrets that are only transmitted from teacher to student.
