Damascus Steel: What is it and Where Did it Come From?
The fabled Damascus steel, whose elusive forging process was guarded by a select few, has seen a modern-day resurgence in recent years. For centuries, this unique forging technique was feared lost to history, as all known traditions of creating this superbly crafted, ornate steel disappeared.
Fortunately for professional and amateur metallurgists alike, modern technology and metallurgical science has advanced enough for scientists to discover modern ways to recreate the resilient and exquisitely intricate Damascus steel.
The Reinvention of Damascus Steel
Named for what is now the capital city of Syria, Damascus steel was originally an undocumented forging technique utilized by Near East and Middle Eastern sword makers. While some evidence may suggest Damascus steel dates back to 300 B.C., the first mentions of the famed steel date back to between 300 and 500 A.D.
Western Europe experienced its first real taste of Damascus steel during the Crusades of the 11th Century when the Crusaders witnessed the famed blade’s unequivocal sharpness in action at the hands of the Arab warriors. The ferocity of those Arab warriors with their unique blades gave rise to the legends which spread throughout the Middle East and Europe.
Traditional Damascus steel is identifiable by its various swirling patterns on the flat of the blade. The unique patterns are believed to be derived from blocks of Indian and Sri Lankan wootz steel.
These wootz steel ingots contained a variety of “impurities” such as tungsten and vanadium that, when combined with the traditional Indian smelting process as well as the numerous rounds of layering used to prepare each blade, created the magnificently sharp and uniquely patterned Damascus blades.
The Arabs successfully imported the wootz ingots for centuries. However, as borders altered, wars ravaged and wootz reserves ran dry, the world began to lose touch with the masters of this unparalleled steel. Sadly, by the mid 18th Century, the blades had completely disappeared, as had the techniques for their creation.
A Modern-Day Reinvention
Thankfully, the human race is nothing if not tenacious and nostalgic. Metallurgists, historians and collectors from around the world, coupled with drastic advances in technology, have been able to reverse engineer the general Damascus steel forging process – and, of course, have added their own special touches along the way.
A September 29, 1981 New York Times article revealed that two Stanford University scientists researching metals with superplastic characteristics accidentally recovered the secret to creating Damascus steel. Their research showed that the steel used to create the ancient blades required a high carbon content and a relatively low temperature for the forging and hammering process, which then required a rapid rise in heat followed by a swift cooling.
As an aside for those gory history buffs out there, the “quenching” or cooling process for ancient Damascus steel blades is fodder for tall tales. Legend has it that the quenching process is where the blades derived their magical strength. It was believed forgers would thrust the heated blades into slaves to transfer their strength into the blade, or that the blades were even “quenched” in dragon’s blood. While the notion of quenching the steel in blood to give it strength may seem unrealistic, some modern scientists believe the nitrogen in the blood may, in fact, have strengthened the alloy.
It’s now known that Damascus steel is not a pure metal. It instead relies on a variety of impurities and an imbuement of high carbon percentages to provide the beauty, strength and durability that is paving the way for the modern Damascus steel revival. The plasticity of the heated metal and the durability of the cooled product allows this steel to be shaped into a wide variety of tools, from gears and auto parts to fashionable styled, high-end kitchen knives.
Types of Steel Used to Make Damascus Knives
The steel required to forge modern Damascus blades varies depending on the purpose of the blade. High carbon steel, stainless steel, or a combination of both are the primary requirements. High carbon steel blades are renowned for their sharp edges, while stainless steel blades are known for being impervious to oxidation. Some commonly used steel grades include VG1, VG2, VG10, AUS8, and AUS10.
- AUS8, a Japanese steel produced by Aichi Foundry, is a stainless steel considered to be a mid-level steel when compared to the superior VG10 or AUS10. This steel has a high carbon content allowing for a hard knife but is known for requiring frequent sharpening. This edge retention issue separates knives forged of this steel from more premium quality knives forged of VG10 or AUS10. This allows for knives of this steel to be more affordable and easily mass produced.
- AUS10 is a Japanese steel also produced by Aichi Foundry. It is a stainless steel with a hardness measured between 58 and 60 on the Rockwell scale. While its edge retention is better than AUS8, it’s still an issue for this steel. AUS10 is similar to VG10 and is commonly used to create high-end and kitchen knives.
- VG1 is a Japanese steel created by Takefu Special Steel Company that is primarily a stainless steel but has a higher carbon content than most other VG steels. This steel was the predecessor to VG10. Known for being sharp and producing great edges, VG1 is lacking the addition of cobalt and vanadium, which means blades crafted from this steel are prone to chipping and corrosion.
- VG2, also a Takefu Special Steel Company creation, is a hard stainless steel with a 62 on the Rockwell scale. The carbon content is lower than VG1 and VG10, but its combination with other metals such as chromium, nickel and copper make it extremely corrosive-resistant.
- VG10 is a famed Japanese stainless steel also created by Takefu Special Steel Company that is combined with a specific series of other metals, including cobalt, carbon, chromium and vanadium to produce a steel that is not only free from oxidation, but is also distinctively hard, scoring between 60-62 on the Rockwell scale. VG10 is also known for holding a frighteningly sharp edge, which makes it one of the most revered steels on the market for kitchen knives.

The Nuts and Bolts of Damascus Steel
The creation of modern Damascus steel is still an art form. From selecting the proper steel with the needed alloys and carbon content, to varied temperatures for forging and shaping and quenching the steel, the process is extensive and precise.
For example, F.N. Sharp proudly uses a combination of VG10 and VG2 steel to create our exceptionally sharp and stunningly beautiful feathered Damascus kitchen knives.
From the powerhouse chef's knife and Santoku knife to the multi-purpose utility knife, the versatile bread knife, the slim and precise boning knife, the handy little paring knife and even steak knives, too, all F.N. Sharp knives are made with the same quality materials, from the handle to the blade.

We chose to combine VG10 and VG2 because we believed their contents would create exactly what we were looking for as far as quality and aesthetics. VG10 contains roughly 1% carbon and molybdenum, 15% chromium, 1.5% cobalt, and less than 1% vanadium, manganese and phosphorus, while VG2 is comprised of roughly 1% carbon, 15% chromium, and less than 1% copper, molybdenum and nickel. The addition of manganese to VG10 produces a darker color steel, while the inclusion of nickel in VG2 provides a bright silver tone.
The differing elements of steel also have different purposes. For example, the addition of carbon improves a blade’s hardness, edge retention, tensile strength and resistance to wear and abrasion, while the addition of manganese improves grain structure, hardenability, strength and wear resistance. The addition of chromium, which is one of the most important elements of stainless steel (at least 13% chromium is required for stainless steel) improves harness, tensile strength, and resistance to wear and corrosion.
When creating Damascus, the two steels are stacked into alternating layers to create billets which are then twisted, folded, heated and hammered. Once the billets have been repeatedly folded and hammered, and the hot metal is the proper shade of dark red (light red indicates a high temperature that will lend the metal to cracking), the steel is then quenched to harden the structure.
Finally, the crafter finishes the shaping process by hammering, lengthening and flattening the metal until a unique Damascus pattern is revealed.

How Strong is Damascus Steel and is it Good for Kitchen Knives?
The strength of any Damascus steel product is directly related to which steels were used to forge the blade. Quality Damascus steel will not only provide a beautiful piece with a unique and intricate design, but also a strong blade with a long-lasting sharp edge.
Carbon is the real hero in the creation of a hard, durable knife. While softer to work with, the carbon amounts utilized in the above described steel alloys hardens more so than regular stainless steel, yet also allows for some flexibility in the steel to avoid breakage.
Damascus kitchen knives have been making their way into home kitchens across the globe, thanks to their exceptionally sharp and long-lasting edges and the beautiful patterns that make them an art piece for the kitchen. The combination of beauty and durability allows them to make quick work out of everyday meal prep – and look good while doing it.
Depending on the steels used to create it, Damascus steel provides the perfect ratio of carbon and trace elements of stainless steel to offer the ideal balance of ductility, corrosion resistance, and sharpness – key to any chef’s requirement for a quality knife.

Caring for and Cleaning Damascus Steel
The best way to ensure Damascus steel’s longevity is to follow the manufacturer’s instructions for cleaning and maintaining the blade. It’s important to quickly wash and dry your knives after each use to remove any organic material that would lend itself to degrading the steel.
If you opt for carbon Damascus steel blades, it’s equally important to completely dry excess water before storing away the blades, as carbon blades are prone to rust and corrosion. You’ll also need to sharpen them regularly in order to maintain the edge.
To enhance and preserve the beauty of intricate Damascus patterns, polish the blade with a non-abrasive polishing cloth weekly. Should the blade be for decorative purposes as opposed to utilitarian, regular oiling will keep a bright sheen that also enhances the Damascus pattern.
If you’d rather not deal with the extra maintenance, your best bet is to opt for Damascus steel knives crafted from stainless steel. Stainless steel Damascus is much easier to maintain and, depending on the types of steel used, can be impervious to rust and corrosion. That’s why we chose to combine two different types of stainless steel – to deliver exceptionally sharp, easy-to-maintain Damascus knives for people with lives (as in, ain’t nobody got time to polish and sharpen their knives everyday). We even made sure they’re strong enough to withstand any accidental bouts in the dishwasher so you can focus on spending more time cooking great meals and less time maintaining your tools.
