To add to Kirk's post and to fill in those who have not read Pleiner,

The incidence of having only 1 edge in steel appeared to Pleiner to occur mainly in the region of Czechoslovakia, with welded on steel edges on both sides being more common elsewhere. It also seems to Pleiner that sometimes the Celtic smiths did not appear to always know the effect of their blending, although at times they did have clear design and intent. AS Lang summarizes in her study of Roman sword mettallography, the "celtic" blades appear (generally) to increase in quality as one moves from earlier to later La Tene. The same did not seem to be a constant with Roamn swords, having good and poor examples both early and late.

Attached are pictures of my piled structure/proto patternwelded blade, showing the piled pattern that tended to appear in the Middle La Tene period. The piece is made by Patrick Barta.

Nathan...

That is one fine looking sword... I love Barta's work.

Is there any way I could see the geometry of the hilt from the side?

Thanks

Thanks Nathan...

That helps me get an idea of the total hilt shape. These types of hilts are so hard to imagine just from a plan view.
Patrick seems to know his swords... I like his intrepretation--it is somewhere between the earlier Anthropoid hilts and the later more gladius/spatha like ones.

I just went through some of my stuff to find images of LaTene hilts that still have organic parts remaining. I will try to post it over on the Peter's "Celtic Swords" thread.

Thanks again for the new perspective.

The question of "earliest evidence" has a factual answer, and the 300 BC period artifacts are the earliest "positive evidence" that I have heard of.
As a practical matter, it was could well have been done earlier. If European smiths imported the higher carbon grade ores (prior to the use of charcoal and discovery of local ores) it is a limiting fact that significant trade with other ore rich regions did not really exist prior to 1600 BC. I searched the internet and found a least one research paper that surveyed sword metalury by estimated age. Of over 150 European origin swords dated around 100 AD, over 40% were judged to have been made from pattern welding various alloys due to the fact that varying high / low carbon content bands could be detected (no cosmetic pattern remains due to corrosion.) By 400 AD, roughly 50% of swords (again over 150 samples) were definately pattern welded. By 1000 AD, over 65% of swords were pattern welded with cosmeticaly attractive patterns (high art form at that point.) This gradual progression illustrates that the technique did not materialize and support a market over night. To go from 1st sword to 40% of the "trade secret" market between 300 B.C. and 100 A.D. is probably not realistic. Wootz (and improvements in laminating and pattern welding) spread from India to the middle East in less than 100 years. It is at least a credible theory that someone in Western Europe began experimenting with imported ores as soon as trade permitted it (definately possible by 1200 B.C.)

For all those who love the New Age/ Lost Civilization, you should check out the Biblical story of Noah and observe that metal tillings were stored as keel ballast. Separately, archeological sites in Turkey have been interpreted as evidence of significant forge/ foundry works dating to around 4000 B.C. I doubt we will ever really know who did it first!

Very interesting thread. I yet have to read most of it, today's busy as hell. (It never rains, it pours)

So for quick review, here's the spear tip of 300BC that I mentioned before:
