Staked Plier Pivots on LM PST

Forgive my ignorance, but with regard to the PST, what are Staked Plier Pivots? T-A

Took this photo for you and I believe the term 'staked plier pivots' refer to earlier Japanese version of PST where one side of the pivot is mushroom over the chassis and staked in place.

I think you may have hit on the answer to my question, but only indirectly. The Leatherman PST Chronology Project at Multitool.org at the bottom of page 1 includes a spreadsheet that shows that all PSTs with hollow rivets have staked plier pivots. So, while I don't think that staked plier pivots refers to the hollow rivets you point to in your top photo, that tool must have a staked plier pivot, while the tool below does not. I need to pull out my hollow rivet tool and study it further. Thanks for responding to my question. T-A

Comis, I think I figured it out. Here are three of my Japanese-made PSTs:
Notice that the two on the outside have little triangular marks in the circle where the pivot pin meets the plier jaw. It reminds me of the sun's corona. The tool in the middle doesn't have that. Now zoom in on your tool with the hollow handle rivets, and you will see the same pattern. I think we have solved the mystery, although there are certainly others out there who can confirm or refute my conclusion. Thanks again for your input. T-A

That one on the end there definitely has a staked pivot, it used to be a very common feature in pliers.
I have examples from Kreauter, P&C, Herbrand, PEXTO, and Utica with pivots that are " staked " like this.

Thanks for confirming the meaning of "staked plier pivot". I will sleep better now! It's amazing what you can learn when you get a bunch of nerds like us together on the same website! T-A
