The History Of Swords
Swords are
the basic weapons of ancient and medieval warfare. Swords are slabs of solid
steel, iron and metal with sharp hard edges designed to pummel and cut your
victim target. Swords are badges of honour and symbols of distinction. The men
who carried the swords of battle and combat were unlike the soldiers of today
with their guns and tanks.
Edged
weapons have been a part of our history for as long as records have been kept.
In fact, some of the earliest tools used by primitive man were sharpened pieces
of stone.
Swords and
knives have played a significant role in every major civilization. Even in
today's modern society, swords are used in many of the most important military
or state ceremonies and functions. Think about the commercials for the U.S.
Marine Corps and how they focus on the Marine saber, or the knighting ceremony
performed by the Queen of England where a sword is used to touch the shoulders
of the knighted individual.
The earliest
known swords were made from copper, one of the most common metals available.
Copper swords were very soft and dulled quickly. Later on, swords were made
from bronze. Bronze is an alloy of copper and tin. An alloy is a mixture of two
or more base metals or elements to create another metal with certain specific
properties. In the case of bronze, the combination of copper and tin created a
metal that is:
- Stronger
than copper
- More
flexible than copper
- Stays
sharp for longer than copper
A better
sword was developed with the advent of iron. Iron ore was easily found in every
part of the ancient world. Iron ore contains iron combined with oxygen. To make
iron from iron ore, you need to eliminate the oxygen to create pure iron. The
most primitive facility used to refine iron from iron ore is called a bloomery.
In a
bloomery you burn charcoal with iron ore and a good supply of oxygen (provided
by a bellows or blower). Charcoal is essentially pure carbon. The carbon
combines with oxygen to create carbon dioxide and carbon monoxide (releasing
lots of heat in the process). Carbon and carbon monoxide combine with the
oxygen in the iron ore and carry it away, leaving a porous, sponge-like mass
called a bloom. The bloom was then hammered to remove most of the impurities.
The resulting metal was easy to work with, but iron swords did not hold an edge
well and were still too soft.
Iron became
the metal of choice for swords and other weapons, and helped forge new empires.
Both iron and bronze weapons and tools made an incredible impact on the balance
of power during the eras of their respective prominence. In fact, those periods
of history are now known as the Iron Age and the Bronze Age. Eventually, steel
was discovered. Steel is an alloy of iron (ferrite) and a small amount of
carbon (cementite), usually between 0.2 and 1.5 percent. Steel was originally
made using a

Process
called cementation. Pieces of iron were placed inside of a container made from
a substance with a very high carbon content. The container was placed in a
furnace and kept at a high temperature for a length of time that could range
from hours to days. During this time, carbon migration would occur, which means
the iron would absorb some of the carbon from the container. The resulting
mixture of iron and carbon was steel.
Almost all
swords made today are some type of steel alloy. In most modern steels, there
also are a number of other elements. You'll learn more about the various steel
alloys later. But first, let's talk about the tools you need to make a sword.
Sword Care and
Maintenance
Simply treating your edged weapons with respect and care
will easily keep them looking brand new for many years to come.
Sword Wielding
All edged weapons, battle ready or not, may injure, kill
and/or become damaged if used improperly. Follow these simple do's and don'ts
to safely enjoy your sword(s) for years to come.
Use common sense
Do not swing any edged weapon carelessly. Keep in mind that
your sword, battle ready or not, is still a weapon that can injure or kill
someone. Although we all have a "warrior" inside of us, we are not
always on a battlefield. Make sure you are in an area where you can swing your
weapon without hitting someone or something. Swords can also slip out of your
hands. Selling your sword to pay for a lawsuit settlement is a big bummer. Be
very careful and use common sense when handling your sword.
The Samurai respects his swords' edge and protects it at all
costs
No matter how tough or strong the steel is in any sword, it
will nick when struck against something equally hard. Do not bang your sword
against another sword in theatrical-style duel. Do not bang your sword against
any hard object to test its strength or the "sound" of the steel as
it hits a hard object. In stage plays or in movies, theatrical swords with
wide, thick edges are used. The edges are flat and often as much as 1/16 inches
wide. Such theatrical swords are designed to take the flashy looking punishment
of banging edges together. Your sword is not a theatrical sword. Your sword is
a real weapon, designed so that they could fight in the manner that the
originals were actually used. Since the cutting edges could easily be sharpened
and were often used for slashing, parries were made with the flat of the blade
(not the edges) or were simply avoided altogether. Real swords were never used
for the theatrical style sword banging that movies or stage plays rely on to
liven up action sequences.
Reasonable Use
Do not attempt to chop down a tree with your sword. Such an
activity is guaranteed to damage your sword. Axes and machetes are well
designed for this with the weight of the steel concentrated over the point of
percussion. When you strike a firmly fixed object like a tree or a thick branch
with a sword, a great deal of the blade projects past the object being cut,
causing the blade to bend or torque. It should be pointed out that the
Japanese, who believe in a lot of practice with the sword, used thick bamboo.
The bamboo was resistant to a cut, but didn't have the rigidity of a tree, and
so would not have damaged a valuable blade. For a Japanese warrior to cut in to
a tree would have been unthinkable.
Sword Maintenance
What should you do first with your new sword? Proper sword
care begins as soon as your new sword arrives.
Immediately After Receiving Your New Sword
Factory direct swords will probably come to you with a light
oil or a heavy coat of grease to protect the blades during transcontinental transport.
To remove the grease you may use a solvent such as lacquer thinner or mineral
spirits.
Once you have finished this, apply your light coat of oil or
a silicone spray. You can also wipe it with a silicone coated gun/reel cloth.
In many respects, the gun/reel cloth is preferred as there is less tendency for
dust to accumulate and trap oxygen to cause pitted areas in the blade.
Since it is the natural propensity of steel to rust, you
must properly care for your blades. Blades must be protected from moisture at
all times. If surface rusting occurs, it can be removed with 600 grit or finer
wet/dry sandpaper and some lightweight oil (i.e. gun oil, etc.). If you are
consistently using the blade, the oil will work nicely. (Hint: wipe the blade
with a soft cloth before using it, then apply a light coat of oil before
storing the blade.) For display and decorative purposes, a carnuba-based wax
(i.e. car wax) or a spray lacquer will work quite well.
How to Treat Wood or Leather
Wooden handles may be treated with a light coating of lemon
oil or tung oil to help prevent cracking.
Leather scabbards and sheaths as well as leather covered
handles should be treated with a good paste wax. The scabbard can also be
treated with neatsfoot or mink oil for water proofing, although this is not
recommended for gripping surfaces. Do not store your sword in its scabbard for
long periods of time since the leather traps moisture which can produce rust
spots on the blade.
Rust Prevention & Removal
Rust may be removed from your swords by either chemical or
abrasive cleaning. Regardless of method, cleaning has its risks. Proceed with
caution. Improper use or attention may damage your blades and/or their temper.
Rust Prevention
All exposed steel will want to rust. Touching any exposed
steel, such as your blade, with your bare hands will leave oils and salts that
will eat their way into your blade and eventually leave pits. The best way to
avoid this is not to touch the blade and to wipe off the blade if it is
touched. It is also a good idea to inspect your swords at least annually to
check for new rusty areas and to use fine steel wool or Nev-R-Dull on them.
Don't forget to change the oil, too.
Rust Removal
I know of two methods of cleaning the rust off of steel --
chemicals and abrasion. I'll try to give several examples of each, in order of
weakest method to harshest. Always start with something weak -- it's easier to
take rust off than to put steel back on. BTW, we haven't tried most of these,
and use caution with any chemicals.
Chemical Cleaning
You can use a Sword Cleaning Kit or Nev-R-Dull for a mild
chemical cleaner. It removes light surface rust and dirt, and is safe to use.
It is available at your local automotive store and I believe it is cotton with
a penetrating oil. It is oily feeling and leaves a slight residue on anything
it is rubbed against. Rub the rusty area with a small piece and then wipe it
off. Great for removing rust caused by light handling or humidity. Always test
it on a small area if in doubt. Not recommended for blued blades (haven't tried
it). I have also heard of a product called Flitz Metal Polish . ( recommended
by the manufacturer in Toledo , Spain )
Solvents. The only one I've heard of using is kerosene. I've
heard that if you soak a blade in it for a few weeks, the rust will come right
off. Anyone care to verify that?
Acids. Yup, you read that right, just be careful and go
slow. Start with some mild household acids -- try lemon juice first. It may
take a few days, but check it periodically. Next would be vinegar (mild ascetic
acid), and then Worcestershire sauce. My preference is a mild solution of
carbonic and phosphonic acids that goes by the trade name of Diet Pepsi (takes
about 3 days, followed by some steel wool and nev-r-dull). If those don't work,
A 1 molar solution of a medium-strong acid, such as muriatic or phosphonic
acid, will slowly eat away the rust. Check your pool supply store for these.
They may take a few hours, but check them regularly! They will eventually eat
into the blade if left too long. Strong HCl will eat the rust off in seconds (I
use it to clean rusty tools at work), but I do not recommend this method for
use on a sword. A strong acid will leave microscopic etching, which will give a
dull, leaden look to the blade.
Electrolysis is the process of breaking apart the rust
molecules into iron and oxygen, then binding the oxygen to a more active metal.
One method is to immerse the blade (remove the handle first) in a slightly
basic solution (caustic soda or lye) while it is surrounded with metallic zinc.
The reaction will eat the rust and produce zinc oxide. It is important that a
basic solution is used to prevent further rusting of the steel, and make sure
that the surface to be oxidized is a more active metal than iron. Check a
college chemistry book when in doubt. Do not use aluminum foil, because it is
more stable than iron and will cause the iron to rust away. The process takes a
few hours, so check it regularly. The process can be speeded up by connecting a
car battery to the apparatus as such: negative to iron, positive to zinc. I
have been told that electrolysis can leave a blade looking 'cooked,' and that
it destroys the original temper of the blade.
I've been told that exposure to high heat will remove rust,
but this will discolor the blade and destroy the temper.
Abrasive Cleaning
Oil and steel wool is the most often prescribed way to
remove light surface rust. You know how to use it already, so there is no need
to say more. Scotch-brite pads and olive oil make a good alternative, for the
more kitchen inclined collectors.
Rubbing the steel with a piece of copper will remove rust as
well. Since copper is softer than iron, it won't scratch the surface, either. I
have never tried it before, but I don't think it would take off any patina.
A soft wire brush works the same way, and may be useful for
a sword that is already heavily pitted or scaled with rust. The bristles
shouldn't put enough pressure on the steel to scratch it, so it should be ok. I
have seen wire wheels for drills, and they might work as well. Test it on a
small area first before attacking the whole blade.
Polishing stones are used in knife making, and will give a
mirror finish to the blade. Remember, though, that this may actually detract
from the value of the sword. Also remember this -- it takes a 5-year
apprenticeship to learn to make a Japanese sword, and a 10-year apprenticeship
to learn to polish one. 'Nuff said.
I assume that abrasive cleaning compounds might work, but
that they would leave scratches on the blade. Test a few out if you want to try
this method.
Very fine grit sandpaper will leave scratches, but it is
good for a hard assault on scaled rust. Be careful to only be rubbing the rust,
though.
Sword Storage & Feeding
Just because you don't own a museum-quality display case
doesn't mean that your swords are at the mercy of the elements. Lacking a
museum-quality temperature and humidity controlled lockable display case does
not mean that your collection can't be displayed safely. The average collection
is not damaged by being hung on a wall with steel hooks (not aluminum) or on
wooden display racks. In high humidity areas, though, it is best to keep your
collection stored in a sealed case with enough desiccants to keep the humidity
beneath about 30% to hinder rust.
It is also very important to KEEP SWORDS OUT OF THE HANDS OF
CHILDREN. Children will destroy a sword in a fraction of the time it takes
rust. Also keep swords out of reach of people who want to clash blades like in
the movies or cut down trees with them.
Long Term Storage
If you do not wish to display your swords, the most
important ways to protect your collection are to protect it from rust, skin
contact, and theft. A gun safe will protect it from all of these. If that route
is unavailable, however, we recommend either using a gun sock or making a sword
bag. In either case, we recommend placing a few packages of desiccant in with
the sword to keep humidity down.
Blade Coatings
Your blade, being steel, will appreciate regular coats of a
clear, non-organic, oil. This prevents moisture from reaching the blade, as
well as giving a nasty sliming to anyone who touches it. Collectors of Japanese
swords recommend choji, which is mineral oil with a small amount of clove oil
for scent. We also recommend a light oil such as sewing machine oil or gun oil.
We've heard of using 10W30, but can't comment as its usefulness. Oil should be
changed regularly by wiping the blade with a soft cloth until dry, then
applying more.
Cosmoline, a Vaseline like substance, and grease were often
used in the past, but now are getting looked down upon. If you have an old
blade covered in it, rest assured that it will still be protected, but there
may be microscopic pits in the blade that would make a collector of Japanese
swords cringe. The stuff is quite ugly as well, but at least it keeps hands
off...
Another option is to apply a wax coating. We've heard of
using carnauba wax (like on your car), but cannot comment to its long term effects.
You might want to check your local automotive store/department to ask about
which waxes are best on steel.
The final viable option is a clear varnish. Del Tin, a
respected maker of medieval replica swords, puts a coat of varnish on their
sword blades. We recommend making sure there are no fingerprints or specks of
dust on the blade first, or else they will eat into the blade from beneath the
coating. |
