Early 1st cen. AD Germanic double edged sword

[Harjaz]

I was hoping to make a double edged 1st cen. AD Germanic sword. I found a replica on the Archaeoschmiede of a double edged sword dated about 0AD from a grave find near Hamburg. It has a lot of Celtic influence, but it is a good example of a sword from the early 1st cen. AD. However, I'm having trouble finding pictures of the reconstructed blade, and how the blade was constructed. I don't believe it was pattern welded, but the site mentioned some type of chemichal process used by the Celts to work the metal. I was also wondering if anyone knew how common these swords were in early 1st cen. Germania. The single edged swords were deffinately more popular, but were the double edged 'Celtic' style slashing swords only in the hands of nobles, or were they available to professional and richer warriors as well? Here is the link to the Archaeoschmiede's sword:
