Bolster attachment on Kiwi, Kopa

[arty]

Does anyone know how the bolsters are attached to the liners on knives like the Kiwi or Kopa or Mini Persian? It is obvious how the knives go together on knives with scales and liners and screws, but not so obvious here.
I also wondered why knives like the Kopa with carbon fiber inserts seem to use nothing more than epoxy, but other inserts require pins.

Not really sure, I'd assume they're either pinned, soldered, or both. Know the pivot pin goes all the way through them, you can sometimes see a faint outline of it on the front bolster. On the Persians, the lockbar pivot pin goes through the bolster as well.

As for pins vs epoxy, I don't think pins are ever "required" anymore, but there are two things at work. Tradition would dictate pins, at least with natural materials, but in some cases using epoxy with those materials is a concession to ease of production. Stone and pearl, for example are hard to drill without chipping and tend to crack easily when a pin is set. Other times, it's strictly an esthetic decision. The first pilot models of the red bone Kiwi had pinned scales. Sal thought they looked too "busy" and opted for epoxy on the production version. Me, I think the pinned version looks classier.
