Damascus Steel Isn't What You Think! Asian Crucible Steel in Medieval Europe

The legendary Damascus Steel has achieved mythical status in bladesmithing. Swordsmiths, blacksmiths, reenactors, metallurgists, historians, and archaeologists the world over have spent decades trying to reconstruct the techniques required to make this super material that enthralled all those who encountered it.
But real Damascus, or Wootz steel was not just specially pattern welded, but also smelted in a specific way, and had specific materials and techniques applied to it, almost as soon as it was extracted from the earth. Many, including crucible steel making, were not available to medieval Europeans.
So, join me as we have a little chat on an old castle about cool steel that people in the Viking Age really liked a lot! We'll also discuss what Damascus Steel isn't, and why you might want to exercise caution before you buy a "Damascus Steel" sword for your medieval reenactment kit!

[@nickverbree]

Yay! A topic I can help with some specialized information in the form of a mile long comment! So, to start off: everything Jimmy presented in this is roughly accurate. Unfortunately it misses out on a bit of the nuance that's involved in modern blade industry nomenclature. The confusion regarding what is damascus steel is actually goes back to European gun barrel makers. High end gun barrels (mostly shotguns) were made by pattern welding steels of different carbon contents together and manipulating them to create visual interest. These have been called "Damascus" in the firearms industry for much longer than what we have seen in the cutlery industry. The current issue is a result of a smith named Bill Moran. Moran was one of the founding members of the American Bladesmithing Society, one of the world's preeminent organization for qualifying bladesmiths. In the late 1970s Moran was seeking to replicate the APPEARANCE of damascus steel, and clearly knew about the connection between pattern welding steel and the "damascus" term used to refer to gun barrels. Moran's big contribution to the confusion was that when he developed a method of pattern welding using a high nickel steel to allow for much more dramatic pattern contrast, he called it "the NEW damascus". The technique was adopted into the ABS curriculum as a demonstration of forging skill and, unsurprisingly, the "new" part was quickly dropped. As the ABS has a HUGE influence on trends and publicity in the bladesmithing world, their use of the term "damascus" is essentially now a piece of trade jargon. To try and avoid it, a lot of smiths avoid using the term at all; instead we'll use "pattern welded" for it, and "wootz" for modern reproductions of the original crucible steel.

[@judgeflems]

Thank you.

[@fciron]

Thanks. I also came here to say that almost no one in the knife industry is using "Damascus" deceptively. It's a result of historic ambiguity in the usage. O

[@andyc750]

the ABS is almost meaningless outside the States, you can blame all that on Forged in Fire etc for spreading the misinformation across the world, just like Hollywood and the katana myths

[@habituscraeft]

Where does this term "wootz" come from? It doesn't sound very Dravidian, to my ears (though I only speak Malayalam, not Tamizh). Is it European?

[@IPostSwords]

​@habitus.craeft "wootz", as far as we can tell, is first mentioned in 1794 by a British merchant as a translation of Tamil utsa. See DOI: 10.1007/s11837-014-1154-1

[@nickverbree]

Just to be clear about something Jimmy said: a patterns welded blade is not inherently better or worse than any other modern mono-steel... But it is VERY labour intensive. If someone is offering a pattern welded sword for sale, expect it to be several times the price of a comparable plain steel sword. With pattern welded "damascus" you absolutely will get what you pay for.

[@donaldwert7137]

I once saw what must have been pattern-welded knives at a rock and mineral show. In my ignorance (thank you Jimmy, for enlightening me!) I asked if it was Damascus steel. The seller, who was the knife smith, was noncommittal, and now I know why. They were beautiful, however, and if I ever see him again I want to buy one for ... reasons?

[@TheSaneHatter]

A long-ago book that I read, said of the various "Damascus'" steels, "all three offer a chance to make a great blade, along with a splendid chance to fail."

[@jessicazaytsoff1494]

When I have seen fancy patterned knives on food shows it seems the pattern goes away with sharpening. I'm hopeful that this is not the case with Damascus or pattern welded?

[@nickverbree]

@@jessicazaytsoff1494 regular sharpening shouldn't do anything to the pattern. If you end up abrading the flats of the knife it will, but most smiths etch deep enough that it really shouldn't be a problem.

[@sidekickbob7227]

I would advocate for a modern high quality steel to be better than a pattern welded steel. Not as pretty, and not as satisfying to use, but for sure better.

His pieces sell in the thousands and tens of thousands because each piece of glass or tile was handmade first before being cut. I also know someone who works in fashion, and we think those expensive gowns are just flashy clothes, but there's technique involved down to the weaving of the cloth that's been passed on by cultures for generations that go into each of those fancy dresses.

You know how in early 2000s it was discovered that true Damascus steel has carbon nano-tubes in it? Well a few weeks ago I was checking up on the reserch into how this could have been achieved. Mind you, I did not see onee reference to anyone involved being a master smith. Just a load of physics. Apparently they are now well on their way to declaring that it was made either with ore or additives that no longer exist. You know, because they cannot recreate the technique, so it had to rely on things they can't get anymore, can't be they just can't figure out the very specific sequence of actions the ancient masters.

[@allangibson8494]

Damascus steel when analysed shows about 0.3% manganese, molybdenum or vanadium and 1.5% carbon. Basically it is a chrome molybdenum carbon steel alloy.

[@MrVvulf]

The research team you'd be interested in was comprised of 3 people: World renowned metallurgist John Verhoeven, Vice President of Nucor Steel Bill Dauksch, and Master Bladesmith Al Pendray. The scholarly paper produced is entitled "The Key Role of Impurities in Ancient Damascus Steel Blades", which is as simple to find as a copy/paste into Google. There is a video you will want to watch entitled "The Secrets of Wootz Damascus Steel" on the channel Loades of History, which is owned by Mike Loades, the BBC ancient warfare expert. The video is outstanding, and not to be missed by anyone seriously interested in "real" damascus. The team not only figured out the actual ratios of materials in the original wootz crucible damascus steel...they were eventually able to reproduce it. Unfortunately, the man with the skill to do so, Al Pendray, passed away in 2017.

[@ltlbuddha]

Notes: Hard and tough are two different qualities when talking about steel. Tough means resistant to breaking and hard means, well hard. Hard steels hold an edge better, but tend to be more brittle.* There are different techniques to try to get a blade with both qualities. Damascus was one, as are heat treating, lamination, and pattern-welding. A note on pattern welding, aka modern Damascus. There are varying qualities as well as fakes. The number of layers means higher price and supposedly a better end product. The types of steel used makes a difference in quality as well. *This is a simplification, but it gives the general idea.

[@linr8260]

I do like some nice pattern welding too honestly but this is fascinating 👀

[@ethanspearman3842]

Also worth mentioning that while pattern-weld is *not* Damascus, it *is* historically accurate to the Viking age/migration era, as there are plenty of examples of spears and swords from that time which had pattern-welded blades, even some exhibiting complex, expressive patterns that suggest that this was an art form in its own right

[@ihcterra4625]

Yes, pattern welding was around long before they had Damascus patterned blades. They didn’t start calling pattern welded blades Damascus blades until they were tying to capitalize on the reputation of Damascus pattern blades.

[@andyc750]

@@bigoldgrizzly I know but that is due to slag in the material and why it was often folded so often, it is wrought is very different to pattern welding and true Damascus, the pattern is like the grain in a piece of timber

[@bigoldgrizzly]

@@andyc750 Quite so, One of the reasons I love working with wrought iron is the fact that it has this inherent grain rather than a bland homogeneous modern steel. It would certainly been the most easily available and most used material, with inserts of expensive higher carbon steel to give a better quality blade edge. Etching gives a subtle effect far less pronounced than that of pattern welded steel.

[@williampanagopoulos656]

This whole damascus vs pattern welded thing is a bit tricky in terms of nomenclature .. Because i get the feeling that as the 18th and 19thcentury wore on, the term damascus became maybe a catchall term for any patterned steel We have, for example, 'damascus gun barrels' as a term where rifle, shotgun and musket barrels were made of 2 or 3 bands or iron wrapped in a helix around a mandrel then welded This had a variety of names but was sometimes known as twist damascus barrels in the 19th century and even earlier One article alleges( key word) that some 17th century gunsmiths were even trying to directly imitate the crucible steel blades of various ottoman and other eastern troops

[@esmecat]

interestingly, my first introduction to the idea of pattern welded steel came in the 90's when i was exploring polymer clay techniques. there is a technique used to create many layers of different clay colors (sometimes including translucent) and running them through a pasta machine to press them thinner. manipulating the resulting stack with impressed patterns resulted in a wood grain or watermark design. the technique was called Mokume-Gane and traced back to Japanese/Asian metalworking practices of the same name. about 10 years later, i had my second exposure to pattern welded steel in the form of a video about the search for the lost techniques of Damascus steel. there they gave a similar (though less researched) assertion that pattern welded steel was not the traditional Damascus steel.... long before the internet was covered in options to buy. in defense of the sellers labeling their work as Damascus steel nowadays, in all likelihood, the don't have much choice. SEO driven traffic controls a lot of commercial success online nowadays and it has changed the way terms are used based on what attracts views. i notice this a lot with wool. if you are looking to buy wool for spinning, almost all prepared wool will be called roving, for example, even though the majority of what is available is combed top. people who are new to the craft have a hard time learning the difference because of the ubiquitousness of the term, and so the term is used more often in what becomes a feedback loop. those who know better can't avoid it without losing traffic.

I actually have several modern pattern welded blades, including a sword, an axe, a Seax, a "Talon" blade, a small hatchet-like blade, and several knives, including a folding knife. They are very sharp and I love the patterns in the steel, which makes them look quite magical - the small hatchet is a pattern of spots and rings resembling "eyes", the pattern in the Seax looks like a series of large fingerprints along the blade, the sword almost resembles the patterns of a topographical map of a series of hills or large mounds, the rest are various styles of wavy water-like patterns. I love them all (16 total currently, the lowest cost was $45USD for the folding knife, the highest was $225USD for the sword) and I have no illusions of them being anything but modern pattern welded blades (and good quality ones too). I'm currently in the process of creating a series of leather sheaths and scabbards for them all, some of them built into a cross-body shoulder bag made from a silver fox pelt (loosely based on a badger pelt black powder "possibles bag" and a similar muskrat pelt shoulder bag my mother made in the mid 1970's), some built into a kind of backpack made from a coyote pelt, some made to attach to a belt or baldric (the folding knife is going into a cleavage sheath 😆).

I remember at university thinking it was likely such skills that got my ancestors their name, though the skill with horses was the one that was passed on right to my dad's generation.

Compare to "normans" in the northeast of France., Not "french vikings", but settled Northmen...

What an awesome video, historical metallurgy is so cool. Who knew "true" damascus had such a drastically different process to pattern-weld, I always thought they were more similar. It should also be noted that pattern-welded steel is also historical to the Viking period and before (I believe the Sutton Hoo sword was pattern welded), and like damascus, can also be stronger than the sum of the steels used (if good steels are used, you can also just forge weld pure iron and weld steel together and as long as they have different carbon contents/ trace metals in them, they will make a pretty pattern. The result will be pretty, but weak). It is not as strong as damascus was purported to be, but pattern welded blades were still considered high-status weapons due to the extra time and skill involved, and they were probably more common in Scandinavia than true damascus because the materials could be sourced much closer to home. All this to reinforce Jimmy's point of if you want a pattern welded blade because you can't find true damascus, go for it, just make sure the steel is actually two different steels as opposed to a cheap monosteel that's been laser-engraved or, heaven forbid, painted.

[@krissteel4074]

Wootz is still around and there's a few people that will make it, its essentially a high carbon content of about 1.2 to 1.8% with some vanadium in there for hardness, some trace chromium and the rest is a crucible process. What got lost over the years was the ores to make it, most of the mines in India and Syria were depleted some time ago a bit after the 18th century. Its quite a difficult material to use in the sense that its a bespoke melt when you get the end product that isn't going to react exactly the same as the material in a similar melt that's done roughly the same time and that comes back to how its processed and ultimately heat treated. You can't really give it very high temperatures during the refining process or it burns out all the carbon and generally the hardening and tempering process is about as variable. There is even some apocrypha that in some steels where not even hardened and hammer-forged out almost completely cold in some sort of age-hardening process that I'm kind of so-so on taking for what its worth but I'm hardly an expert and this video just popped up in my list on youtube (but I am a full time cutler) Needless to say, wootz is a completely rubbish material for industrialised processes and really the other reason that people threw it in the too hard bucket, no ones rolling up to your merchant to order 30,000 munition grade bayonets, sabres and other pokey objects from your foreign sources- they went to England, Germany, Spain, France and Italy when they wanted a lot of metal objects to fit out the vast armies of the time. Leaving the bespoke manufacturers of such things to just local demand from whoever. Its why you see 'trade blades' from about the 16th century onward show up in everywhere from central Africa with a Solingen proof or in the Americas from the Brits, French and Spanish. So even while they 'could' make their bespoke crucible steels, even the people who could, wanted more and the European processes was BETTER in the sense you have more blokes in the field with a sharp object that was functional than the other guy and the real killing began. Add to that, swords really only had a use up until blackpowder was being phased out as your 'better than nothing' alternative in a gun fight and the gun itself was probably the greatest equaliser in terms of warfare over time that further diminished the importance of edged weaponry. In terms of wootz today versus modern metals, there's no comparison really. Our modern metallurgy has left it in the dust long ago to the point something like our basic UK or US produced 1084 steels would outperform anything made in the per-industrial era by a very large margin. Plus when you buy it by the bulk in an order, every tonne you have will heat treat exactly the same as the last sheet you cut up and will be perfectly serviceable. That's just basic 1084, the newbie starter steel you give the up and coming knife makers to use, practice on and can make a blade better than some master in the 17th century in terms of shock resistance, hardness and edge holding and its 'barely' a high carbon steel at 0.8% carbon content. Then look at the high alloy, modern tool steels- these are many generations better than anything else, they're super fine grained, insanely tough, have edge holding for days and essentially makes the modern world what it is by those properties alone for machining tools. Somewhere if you want something that will put up with a 500kw, 12000nm of torque shredding machine that eats car bodies and engine blocks for breakfast it'll have teeth and blades made out of something like S7 or A8Mod and that's commonly available to anyone with the cash who wants to make a knife out of it. (I do sometimes and its absolutely bonkers!) So wootz had its time, but its more or less an artisan hobby and has been for about the last 3-400 years as industrialisation wiped it out, its pretty cool, you can still make it. Actually making anything out of it takes a lot of work though so its hardly economically viable to do those melts for people without some kind of extra funding to do it.

Damascus steel comes originally from the area of Damas and then suddenly ppl are calling it damascus steel, but many sites have been found all over the area of Damas. But what ppl see all over the internet is cheap made, even crudely made with alot of imperfections in it. Pattern welded steel is what the vikings used etc. I am glad you mentioned Damas and the misconception that ppl think it is damascus steel. Tack från Sverige.

I recently saw a piece about someone finding a deposit of iron near damascus that has the right combination of mineral impurities to be used in "damascus" steel.

[@TheWelshViking]

That’s the Warda mine in Jordan. There’s precious little evidence it was exploited to make such wootz steel, because that required specific techniques, but it is metallurgically compelling!

A friend of mine told me that modern items sold as Damascus steel are often made from Ex Cold War tank armour.

[@evilwelshman]

So, considering the material is so much more superior than the local steel used at the time in Europe during the Viking period, I wonder if swords made from Damascus steel contribute to legendary swords that are described in folklore. Also, Damascus steel was used to make blades like swords and knives. However, is there any record or evidence of Damascus steel being used to make other weapons, such as axes, spears, or arrowheads?

[@mzgreenjeansapproves]

So off topic, I remember seeing a Bollywood movie Baahubali and there was this scene where they were testing swords. And none of them were good enough for the protagonist 😂😂😂. It's interesting that real history supports that ridiculous amazing epic film.

I don't know anything about metalwork, but this is nice to know.

[@sharktoothjack8854]

I think it's cool to think about having experiences in common with historical people about mundane things like trying to buy something and finding out it wasn't what you thought it was. It's cool how much historical metalworking is relative to what materials and tools are available concurrently. I don't think it's surprising that most modern smiths aren't replicating ancient techniques! The technique seems unlikely to be suited for the materials and equipment that modern smiths can find

Does the damask fabric have that name for the same reason, the patterning? I think I've heard it called watered silk.

[@TheWelshViking]

Yes!

[@kellyburds2991]

Damask is named for the city, but it's actually a type of very intricate weaving that results in a pattern on the front and back of the fabric. Watered silk, aka moire, is a finishing technique that involves getting silk wet and pressing it between rollers.

Just a note on scandinavian iron at 10:30 - Scandinavian bog ore and the iron/steel you get out of it is actually of very good quality (swedish steel was incredibly sought after up until like 1980 :)). Sure, the iron age bloomeries are incredibly resource consuming and only yields a few kg's of iron compared to the medieval blastfurnaces, but the quality was 🤌

[@TheWelshViking]

I mean… not really all that good in the period at all tbh if we’re talking Denmark and Norway

[@mf8279]

@TheWelshViking True. Norwegian ore had a lot of phosphorus, making the tap bloom more common there to avoid the iron becoing too brittle. Denmark on the other hand, with their bedrock? Can't even begin to speculate. Cool thing is also that there is evidence that "swedes" around Uppland began experimenting in rock ore during the vendel period and that some of the fellas in the Vendel graves might have been Bergsmän (magnates owning part in a mine). So i think quality was likely never a general issue when it came to weapons. Quantity however was. Production of weapons in scandinavia would be nothing compared to the quantity produced by the franks, holy roman empire or brits:)

[@wintyrqueen]

So, was the steel made as a raw material & then smithed into a sword afterwards, or did it have to be made into its final (or near final) form during the initial process?

[@Alphqwe]

Tod at Tod's Workshop KZbin has several videos on pattern welding Viking swords.

[@TheWelshViking]

[@nilsb.830]

As a blacksmith I am aware the modern use of Damascus is referring to different alloys of steel welded together (mostly involving some manipulation like twisting to get more complex patterns), nonetheless this is an actual historical thing to do there are hundreds of the pattern welded blades/spears/axes/guns and what not throughout history from Roman swords to Ottoman guns and the patterns can go insanely complex and they really knew what pattern they wanted and how to get them. As mentioned iron quality wasn't the best and folding and welding is a way to get impurity's out and one theory is that the patterns occurred to demonstrate the blade smiths skills because you can spot flaws and the more complex the better the smith so you knew it was high quality and wouldn't snap the first blow you hit. Different alloy occur naturally depending where the ore originated from so iron from Germany might be harder, hold edge better but is slightly more brittle then iron from England but combined they make a better sword then alone you can actually pattern weld the same steel as the carbon is drawn towards the weld, different alloys just make it pop more (like nickel gives a more silver line) every time you heat a piece you lose some quality so pattern welded steel can never be better then modern steel all this just to say modern Damascus isn't historically inaccurate it just didn't go by that name, pattern welding is insanely hard especially if you want to recreate the same pattern as every thing you do differently impacts the final results and you can say about ancient Damascus what you want but we can't be certain as we still haven't figured it out. anyway love the video keep up the good work btw for those whose patterned blades are fading: soaking it in used coffee grind should bring it back at it is slightly acidic but doesn't eat the blade like more aggressive acids... unless you have been scammed and the pattern is just etched in :o

[@wiredrabbit5732]

I must say (as a guy who has done some blacksmithing and made my steel from sand and carbon) that much of this is linguistics. "Damascus" in modern usage IS pattern welded steel. It isn't a scam, its just how the word is used. Well educated smiths will make a distinction. But in a world where people call everything runes and can't tell elder futhark from younger do you really think they can speak to the structure in iron alloys? Language changes. You know. As an engineer i perked up when you mentioned wootz and crucible ateel because in discussions of "Damascus" these terms come up often as do terms like Austenite and Martensite and occasionally tamahagane. It is complicated and i do appreciate the video.

[@OldZean]

Yay a video i know stuff about. Maybe I can contribute some knowledge..........nope..... That pretty much covers it ^^

[@jakeaurod]

My dedication and expenses for historical re-enactment limit me to swords constructed of cardboard and aluminum foil.

[@tinanyman5084]

So my old shotgun (father's, father's and so on scenario) has what are called damascus barrels, but they are really pattern welded steel? Doesn't sound anywhere near as romantic.

[@scollyb]

Weird thing is pattern welded swords (at least of certain types) are more historically accurate than wootz I'd go further, if someone is selling something called Damascus steel it's pattern weld. The few smiths trying recreate accurate Damascus use the name Wootz

[@MrSinclairn]

Excellent and interesting vid,Jimmy,should have done a more obvious in-depth colloborative tie-in with 'The Shogunate' channel,as the Japanese (samural) swordsmiths,then and now,are 2nd to none ! 👌👍

[@TheWelshViking]

Mmmmmmm they did/do a lot of folding, but they had to because their iron sucked. Arguably claiming they’re the best in the world dismisses the 1000+ years of exceptional skill in India and Persia that was very advanced. Shogunate had their own plan, and an obvious tie-in isn’t either of our styles, or in the spirit of the wider collaborative effort :)

Roselli in Finland is making what could be pretty close to Damascus/Wootz.

[@jesskg12]

This is really interesting! Are there times where a pattern welded blade might be more historically accurate for a reenactment than one made from crucible steel? My understanding was that a lot of early Viking swords (not the Ulfberht ones) had pattern welded blades, not "Damascus"/crucible steel ones.

[@TheSaneHatter]

My own limited knowledge suggests that pattern-welded steel was most widely associated(?) with the Migration Period, between the fall of Rome and the Viking Age. There's said to be one MOTHER of a seven-core pattern-welded blade in the Sutton Hoo burial. Still, it wasn't unknown to the Norse.

[@andyc750]

@@TheSaneHatter pattern welded steel was known about and made before the Romans and they themselves used it for a lot of things, it was developed in the iron age and the Celts mastered it long before the Roman empire came about

[@draxthewarlocktitan5217]

So to clarify not all pattern welded folded steel is Damascus steel. But is Damascus steel also a type of folded steel but using a very specific forging technique? Like is Damascus folded steel or a mono steel?

Damascus is a form of steel made from a specifically crucible wootz steel made using iron with specific trace element inclusions

I have a question for nitpicking Jimmy (Any of the Jimmys will do 😉). How does the japanese forging and metallurgy compare to damascus steel? I would love to hear your toughts on this. Thx! Greetings from Hordafylkir.

[@TheWelshViking]

Japanese iron was generally absolutely awful, hence the need for extensive folding and forging techniques/m. But I’m no expert!

[@judgeflems]

@@TheWelshViking Thank you! The reason for me asking this, is that to me at least, the steel used on the japanese swords looks a lot like damascus steel/folded steel. Nowadays it is all the rage, even Ikea sells knives in "damascus steel". Again, thank you. 👋

[@nickverbree]

@@TheWelshViking that's actually a really nuanced question with an equally nuanced answer. The ORE available in Japan is generally low quality, that is to say low yield, and it is very difficult to smelt due to it being extremely fine particles. That's why it's provided in a specific variety of bloomery furnace. That said, once the smelting process is complete, the technique yields a relatively high carbon steel bloom that retains enough carbon after repeated forge welding to make excellent blades. Ilya from That works channel did a piece all about steel comparisons that's a great watch, and it comprehensible to non experts. I shall go find it and attach it in another comment
