Default Question about Damascus blades

Hi all. So in my limited knowledge about steel I was hoping the CG community can educate me.

From what I understand, Damascus was process in which impurities from inferior/lower grade steel was eliminated by heating the folding that steel. Most notable examples of this process is the Japanese katanas.

Given it was a process to "make better" the poorer quality steel. If we start with a great quality steel (that we have with modern metallurgy) and use the same Damascus process.....does that make that already great quality steel better? Or is does it just add cosmetic value only?

Don't know if it will answer your question, but the vid at this link - http://www.thetruthaboutknives.com/2...amascus-steel/ - is pretty interesting.

Any modern super steel (s35vn , s110v, d2 etc) will far outperform ancient demascus ***if heat treated properly***. However demascus today is usually made with two contrasting steels to highlight the pattern. There is even companies who make stainless demascus such as damasteel and Nichols demascus. Very beautiful very expensive.

If you like demascus look into a knife with a hamon. It is a single piece of steel differentially hardened.

forgot to add, nothing wrong with a modern demascus knife at all. I love the different patterns. But the ancient stuff was great in its day.

Thanks, but is the modern Damascus (mix of two modern steels) far better than just one modern steel? Or is modern Damascus only for aesthetic reasons?

The folds of metal allow for impurities to form and can be difficult to burn away, that is not a good thing. It's an ancient process, using ancient technology.

Ok first off, the purpose of folding blade metal is to spread out the impurities. It doesn't add more. [Edit: Some smiths will intentionally add things to alter cabon content, but folding is just folding.] If you have a concentrated chunk of something in the steel it causes a weak spot. Spreading it out by folding it is the basic way to make a homogeneous piece of metal.

Second, japanese "folded" steel is a misnomer. What they are actually doing is laminating and forge welding, not folding. This lets them use a hard and brittle steel for the edge and keep it from cracking by reinforcing it with a soft and tough steel.

Modern blade steel is a wonder metal compared to anything more than 200 years old. "Damascus" today, is just a decorative pattern. All the properties that people look for in "damascus" can be had in other types of steel, both with or without the pattern.

Wootz is the original damascus steel made in India starting around 2000 years ago. It is a monolithic steel in that it is not laminated or forgewelded into layered steel. The patterns in wootz are formed by dendrite crystals which give the steel strength like rebar in concrete.
Pattern welded steel was made by forge welding layers of steel to achieve a billt with fewer flaws. This was done both in Asia and Europe.
Pattern welded:

Modern forge welding will not make a modern steel better. It can make it worse, cold shuts, slag inclusions, overheating etc.

Not sure if this directly applies but you're supposed to avoid and not shoot guns with a Damascus barrel because they are not as strong.

WOW....thanks guys....I was hot and heavy for modern Damascus blades, but I can live without the beauty of it esp when you are paying a pretty penny for the same quality out of a regular blade.
