How do they do it…?

Last night I was talking with my roommate about the composite leek, and for some reason he doubted that it would be possible to mass produce it, and doubted that it would be possible to make the blade in the manner in which I described its being made. This was understanding since my knowledge of this particular technical aspect is next to nothing. Can anyone help me out here and give me a way to explain how they did it?
 
Cut out the two pieces (laser I think), and weld them with a copper bead. Etching then brings out the contrast.
 
He maintains that shouldn’t be possible, not quite clear why. Is there something we’re missing or does he just drink to much?

With any luck I’ll be able to catch him sober. If I remember right he was telling me that despite the two steels being wielded together you would still need something more to keep them that way.

Like what? Super-glue? Does your friend work in the manufacturing business? Is he a metallurgist? Or is all this simply conjecture on his part?

I should think that the price alone would be evidence enough that it was mass-produced. Either that, or all those custom knives I keep seeing from various "makers" are waaaaay over-priced! :D

He tells me that he has a good grasp on wielding and such beyond that he doesn’t know much of anything about manufacturing. He kept saying that there was something missing, joking aside the way he described it almost did make it sound like supper clue.

Lol all I was trying to do was talk about a cool knife that I’m thinking about adding to my collection and it winds up in another argument. The argument did however make me realize that I knew almost nothing about how they actually did it.
 
If you notice most of the patterns also have a mechanical bond think dove tail joint. If you think of how little lateral force is required to snap the tip off a knife you will have a good understanding of how minor the bonding agent (copper paste) needs to be. They use this same technology for masonry dill bits and other carbide tiped tools, all of which are in mass production.
