I believe there is some ambiguity here when talking about metal working, more specifically about welding and brazing.

Modern welding appeared only by the end of 19th century, with the Industrial Revolution. Nowdays, when talking about welding we normally refer to modern welding.

However, forge welding, wherein the parts to be joined together were heated to red hot in the forge then hammered together, without use of any filler material, was known and used since the Bronze Age. Nowdays, forge welding is commonly referred as simply "forging."

So basically all welded structures made until well into the 19th century were forge welded. And this is the case old the pattern welded blades, and the case of most of the Katars (like for example the the Katar in the original posting) that were made by forge welding together their components and NOT by carving from a single steel block.

Those Katars that were not forge welded, were riveted.

Brazing is a generic term that refers to joining together two metal based components by using a filler metal. Exactly the same is soldering,

The only difference between brazing and soldering is the filler alloy used.
Whereas brazing is done at higher temperatures and accepts a wide variety of filler metals (Copper, Silver, Gold, Nickel, etc. and their alloys like Bronze or Brass), soldering is done at lower temperatures and uses a filler based on Tin (that has a very low melting point).

My two cents...
