Bladesmithing

Bladesmithing is the art of making knives, swords and other blades using a forge, hammer, anvil, and other smithing tools. Bladesmiths employ a variety of metalworking techniques similar to those used by blacksmiths, as well as woodworking for knife and sword handles, and often leatherworking for sheaths. Bladesmithing is an art that is millions of years old and found in most cultures.
The basic art and principles of forging a blade has remained similar for thousands of years and the modern bladesmith uses a variety of tools and techniques in order to produce a blade. Forges formerly fed by wood, coke, or coal are still in use, but gas forges are becoming the standard. Likewise the smith's hammer is being eclipsed by the use of hydraulic forging presses and power hammers.
== Process ==
Though the process varied throughout history the overall process remained mostly the same.
=== Forging ===
A bar of the desired metal or combination of metals is heated in a forge and then it is hammered into the shape of the sword. This hammering process can take a long time and it is called drawing out the sword. The sword is worked on in sections (usually around 6 inches in length) and repeatedly hammered and heated until it comes into the desired shape .This process is repeated many times and the sword is often heated then allowed to cool without hammering. This is required by the metal to keep the desired properties of strength and flexibility. Once this step is completed the sword is in the proper shape but the properties of the metal make it very brittle and something has to be done to give flexibility to it
=== Annealing ===
Annealing softens the sword and makes it easy to grind into shape. The sword is now heated and then allowed to cool very slowly. Often it is wrapped in an insulating material to slow down this cooling. It can take as long as 24 hours and this annealing process makes the sword soft and easy to grind.
=== Grinding ===
Now the bladesmith uses a grinder to work out the edge and point of the sword. This would also be when any engraving is added. This is not a completed sword yet. It is still much too soft so it must be hardened.
=== Hardening ===
Now the sword is heated to a very high temperature and then placed into a quenching tank. This quenching allows it to cool quickly and evenly which will harden the metal. After this hardening the sword is brittle and something must be done to make it strong yet flexible.
=== Tempering ===
Again the blade is heated and quenched. But now the heating is at a much lower temperature than was used at the hardening. This heating/quenching cycle may be repeated several times. This tempering allows the blade to be strong but not brittle. This is one stage where the skill and experience of the swordsmith is invaluable. It takes a trained hand and eye to understand the properties of the meta. It will have a certain amount of flexibility yet still retain its sharp edge. Now the sword is ready for completion.
=== Completion ===
The sword blade itself is now complete. Now the additional parts will be added such as the pommel the guard and the hilt.
== Knives ==
A knife is a tool with a cutting edge or blade, hand-held or otherwise, with most having a handle. Some types of knives are used as utensils, including knives used at the dining table (e.g., butter knives and steak knives) and knives used in the kitchen (e.g., paring knife, bread knife, cleaver). Many types of knives are used as tools, such as the combat knife carried by soldiers, the pocket knife carried by hikers and the hunting knife used by hunters. Knives are also used as a traditional or religious implement, such as the kirpan. Some types of knives are used as weapons, such as daggers or switchblades. Some types of knives are used as sports equipment (e.g., throwing knives). Knives are also used in agriculture, food harvesting etc.; the sickle, the
== Swords ==
A sword is a bladed weapon intended for slashing or thrusting that is longer than a knife or dagger. The precise definition of the term varies with the historical epoch or the geographical region under consideration. A sword consists of a long blade attached to a hilt. The blade can be straight or curved. Thrusting swords have a pointed tip on the blade, and tend to be straighter; slashing swords have a sharpened cutting edge on one or both sides of the blade, and are more likely to be curved. Many swords are designed for both thrusting and slashing.
=== Classifications ===
* Great sword
* Executioner swords
* War swords
* Broad swords
* Long swords
* Bastard swords
* Arming swords
* Short swords
=== Cultural Variations ===
Swords vary vastly in design depending on the time and location of their creation. Despite this most fit into the above classifications expect these listed below
* Rapiers
* Katanas
* Falchions
* Scimitars
* Sabers
== Materials ==
=== Steel ===
The use of a variety of steels to produce blades, most commonly high carbon steel, or a variety of steels welded in layers, commonly referred to as "Damascus".
==== Damascus steel ====
Many bladesmiths are able to forge a special type of steel using a technique called pattern welding, producing a metal erroneously referred to as Damascus steel. Modern pattern-welded steel can be highly decorative as well as durable (if welded in certain ways with proper steels), and is often used in custom knife- and sword-crafting.
