Looking more closely, they're modified Victorinox knives... I know the new scales are titanium (not sure about the pins) but the prices I've seen seem a little crazy for what is essentially a modded knife...
You can get the pins separately - I've just bought two sets for a couple of custom SAKs I want to put together. I paid $31 for six, delivered. They seem very nicely made.
