History of Damascus Steel
How to Make a Damascus Steel Blade:
There are many different techniques that blade smiths
and blacksmiths use to make Damascus knife blades. The
following is a basic method for a fixed blade knife:
Prepare the Billet:
Start with five pieces of steel. Two high carbon pieces
and three medium carbon pieces. (If forging a sword, you
may want to use seven pieces total, instead of five.)
The thickness, width and length of the pieces depends on
the size of the blade desired. One of the medium carbon
pieces should be made longer in order to handle the
billet in the forge. Clean the impurities from the
pieces of steel, then sandwich the two high carbon
pieces between the medium carbon pieces. Tie the pieces
together with wire or arc weld them together at the end.
The wire or weld material must be removed after the
first forge weld.
Weld:
Place the billet in the forge and bring to a cherry red
color. Remove it and cover with borax. When the borax
becomes fluid on the steel and the steel begins to
spark, it is ready to weld. Hammer the pieces together
with a hammer and anvil.
Draw,
Cut, Fold and Weld:
Draw the piece out to twice the original length.
Remember to strike the billet straight down to draw it
out and not to "push" the steel out, in order to avoid
splitting. The billet will have to be heated several
times during this process. Cut the billet in the middle,
but leave a little material to keep it together until
the next weld. Turn the billet on its side and hammer
enough to swell the center of the billet. This will
provide a convex surface for welding. The slag and borax
will be forced out of the billet instead of getting
trapped inside. Clean the billet and reheat. Then fold
the billet back on itself. Add borax and heat to a
welding temperature and then weld.
Repeat:
Repeat the draw, cut, fold and weld process 5, 6, or 7
times in order to obtain 150, 300 or 600 layers
respectively. The more layers, the more skill that is
required for a good looking blade.
Shape:
Hammer or cut and grind the billet into the shape of the
blade desired.
Heat
Treat:
Heat the blade to a orange-red color (1,400 to 1,500
degrees), then quench in a standard quenching oil. A
brine solution can also be used. Temper the blade by
slowly heating to around 400 degrees for about two hours
(depending on the size and material used).
Finish:
Sand the blade, using finer and finer grit. Then polish
and sharpen.
Etch:
Dip the blade in an acid bath. Ferric chloride is used
with about four parts water to one part acid (a fifty
percent acid and fifty percent white vinegar solution
can also be used). For best results, heat the blade to
about 100 degrees. The acid eats away at the softer
metal faster. This brings out the distinctive grain
pattern.
Add
Handle:
The last step is adding the guard, hilt and handle.
