I too have fallen in love with Damascus blades. Joeye I would be really interested to hear how the blade performs. BTW it looks

.
I have been looking at Damascus folders , the special LM with Damascus blade is out of my price range

.
Thanks for sharing mate

That is ruddy awesome!

nuphoria · **Reply #10 on:** April 05, 2009, 01:17:58 AM

What a great custom job to have - can you give us an idea of how much a blade like that would cost?

Poncho65 · **Reply #11 on:** April 05, 2009, 05:22:46 AM

That blade looks brilliant

Lovely design that Damascus steel has

prime77 · **Reply #12 on:** April 05, 2009, 07:15:51 AM

That sure is a beauty!

joeye975 · **Reply #13 on:** April 05, 2009, 04:48:44 PM

I can tell you more details about it! I asked a bladesmith in China to made it who also designed and customed the damascus steel ring for me! The cost of the damasus blade nearly equal with one Powerlock which I can afford it!
And I also be pround to show the ring!

J-sews · **Reply #14 on:** April 05, 2009, 05:46:38 PM

I know nothing about damascus steel (other than it looks great!) Is it a type of stainless steel that will not rust?

About Damascus Steel

The term "Damascus steel" can be used to describe a secret, ancient process of making swords or the modern process of forging jewelry or knives using a layering technique. Either way, Damascus steel also refers to the swirling pattern revealed when etching the final product. The intricacy and beauty of the final configuration, along with the strength and durability achieved through the layering method, make Damascus steel an excellent choice for developing timeless pieces of jewelry.

The origin of the name is as complex as the possible applications of the term. The surface patterns on Damascus sword blades and knives resemble turbulent damas—the Arabic word for water. Another explanation is these swords were made by a man named Damasqui. The most likely source is geographical: the city of Damascus in Syria.

The Ancient Story

There are several theories on the origin of Damascus steel. It can be traced back to India and Sri Lanka (300-100 BC) where it was referred to as wootz steel. This highly purified metal and unique process slowly made its way to the Middle East between 900 AD and 1000 AD where the method was refined. Weaponry made of this steel was commonly produced and sold in Damascus, Syria—a successful international trading center of the time. As these arms spread throughout the area and the rest of the Fatimid Empire, the term Damascus steel was born.

French and English armies first encountered Damascus steel weapons during the crusades. These swords were said to have almost mythical qualities, such as the ability to cut through a knight’s blade or even rock without losing its sharpness. European blacksmiths attempted to duplicate the legendary steel using a pattern welding technique. They even went so far as to etch their swords or decorate them with metallic overlays to match the look of Damascus steel. However, they were never successful in replicating the power and malleability of the superior steel. Metal smiths and artisans in the Middle East continued making Damascus steel swords and knives until 1750 AD, when the legendary process was unexplainably lost.

The Modern Story

Today, the term Damascus steel refers to the combination of two different kinds of steels that are welded and forged into a bar or rod with a multitude of layers. After patterning techniques are applied, the Damascus is etched to reveal the distinctive pattern of those layers; the signature swirling configuration made famous by those ancient weapons.

In Sweden, a new spin on the old Damascus steel process has been developed whereby alternating layers of two different kinds of stainless steel powders are hot isostatically pressed together. The resulting diffusion-bonded duplex steel billet is subjected to traditional steel processing techniques to form round billets which are subjected to the same techniques used by the early metalsmiths to produce Damascus Stainless Steel.

Ahh, so nowadays the hot isostatically pressed together powders form a diffusion-bonded duplex billet?

That's what I thought

MultiMat · **Reply #17 on:** April 06, 2009, 06:03:49 PM

Joeye besides looking 'the ducks guts'(very cool

) do you know is there any advantages of Damascus steel blades over other modern steel blades ?
I would also interested to hear how you find blade edge retention & ease of sharpening of your Damascus blade?
Thanks mate

Damascus steel doesn't denote any specific steel per se, you can forge any two steel together as long as they give contrasting color when acid etched, be it simple carbon steel or stainless steel. So how it performs entirely depends on what steel it's made of.

Nikos · **Reply #19 on:** April 06, 2009, 10:45:30 PM

I've always thought that, if anything, a Damascus steel not done right is at least prone to chipping. Perhaps it's all in the "diffusion-bonded duplex billet" but other than looks I'd prefer a laminated blade any day.

jzmtl · **Reply #20 on:** April 06, 2009, 10:47:31 PM

Never heard of any chipping, then again I'm not really a fan so don't have any. I've seen knives that has VG10 core and damacus cladding, best of both world I guess.

zepla · **Reply #21 on:** April 06, 2009, 11:44:39 PM

It looks very nice though

DaveK · **Reply #22 on:** April 07, 2009, 01:28:09 AM

Wow. That looks amazing Joey - totally unique. I love it.

joeye975 · **Reply #23 on:** April 07, 2009, 01:27:18 PM

Base on what I searched on the web, I can give you more information about the sweden damascus steel! And as the bladesmith told me that the hardness of the main blade he made for me could reach HRC61+.

The following is quoted from the internet:

To create damascene patterned steels using RSP requires that two powder grades be carefully placed into the steel capsules in a laminated or mosaic pattern cross section. Most modern steels can be used to create RSP Damascus. The choice of components is based on the following principles:

Chemical composition of both components must correspond to standard industry-grade steels. Machining qualities and heat treatment for each alloy must also be similar.
The easily diffusible elements, carbon and nitrogen, must not be accumulated in one of the steels. Both steels must have the same carbon-nitrogen potentials in all hotworking temperatures. Otherwise the properties will vary out of control.
The transformation temperatures must be similar. If the components harden at different temperatures there is a risk of deformations and dimensional errors.
The deformation stresses at forging must be similar. Differences too large result in increased hardness and cracks.
Alloy chemistry must differ so each alloy responds differently to the etching bath. One alloy must have galvanic protection from the other metal.
The best combinations of RSP alloys for many applications (hunting and cutlery knives, jewelry, decorative iron-work, gun-receiver hardware, golf putters, axes, and door handles) include 936 martensitic stainless-steel and 958 austenitic stainless-steel Series.

The 936 Series is made from RWL 34 (1.05% C, 14% Cr, 4% Mo and 0.2% V) and PMC 27 (0.6% C and 13.5 Cr) alloys(Which was used to made my sog blade). This RSP damascene steel can be hardened to a maximum of 3HRC over conventional steels without losing toughness (measured as fracture energy in both compressive and bed loaded edge). The material is, however, sensitive to overheating when forged at 1,920 to 2,120°F. That's because the material starts to melt at 2,230°F.

Electrical or gas-fired furnaces are recommended to better control forging temperatures. Compared to normal lowalloy carbon steels, the martensitic RSP stainless steels have higher, almost double deformation stresses. Hand forging must, therefore, take place on relatively small dimensions. Long heating times can also damage the material because of decarburization and scale formation. And slow cooling after hot working prevents crack formation at the martensitic formation temperature (400°F). Because of the cracking risk, no cutting or machining should be done after hot working until the material is annealed for 5 hr at 1,380 to 1,440°F.

Austenitic 958 damascene steel is an alternative to silver. It has good corrosion resistance and is made from two nonhardenable steel grades (316L and 304L) welded together in more than 100 layers. Typical applications include table cutlery, jewelry, and decorative ironwork.

For damascene-steel gun barrels there are two series. The first, 926, are low-alloy hardenable (300 and 400 HRB) carbon steels made from AISI 4140 (0.4% C, 1% CR, and 0.2% Mo) and AISI 4340 (0.4% C, 1% Cr, 0.2% Mo, and 0.2% Ni) alloys. They are designed for bluing and browning operations. The second, 968, are hardenable (300 and 400 HRB) stainless steels made from AISI 416 (0.22% C, 13% CR, and 0.2% S) and AISI 431 (0.23% C, 16% Cr, and 3% Ni) alloys that work well for etched-pattern designs.

Hello
forgive my ignorance please but seeing the blade and learing more about this steel i think
I NEED THAT
was that a purchase? is so where? or is it custom?
Thanks

Edit: whoops, I made a post without reading the whole second page

www.aescustomknives.com This guy makes some interesting patterns with different types of steel and then makes them into knives- he even explains/shows pictures of the process if anyone is interested.
