, you've left me with a little head-scratching, digging through my pic files, and research to do here, but no worries, it's a bit of fun to have later on what's been a most pleasant Father's Day here.
I found these pics of my Hati over at the
disassembly thread. In the first, pre-cleaning pic, the light's a little funny but it kinda looks like the pivot bushing
might be brass...

...while in this post-cleaning shot, the contrast with the stainless pivot screw receiver looks like it clearly is. I honestly didn't recall noting the bushing material from 3-plus years back. I would think it's brass as that's what the washers are and everything would be gliding on the same material. BTW, if you use the link above you can see all the inside Hati pics at that post, and if you scroll up that page aways you'l see a similar breakdown of my RDD CF.

Now as to the 111, that knife is vintage 2018, bought as new from a Russian re-seller here on the Exchange. I dug around through old Imgur files, my phone, and my laptop looking for pics that might show a bearing pivot. I do have a
post in this thread suggestive of one, but really never thought it did. I finally found a pre-cleaning, disassembly pic on my laptop of when I first cracked it, and if you compare what I take to be a concentric mill-out in the lock-side of the blade to the mill-out in in the CF side for the underlay washer and bearing cage along with the comparative sizes of the two sets of bearings it's pretty clear that there's no pivot bushing which would have to extend through to that underlay washer on the show side. My knife must be a later version of the 111.

I'm gonna kick back for now and will come back another time to my take on your other queries concerning usage, steels, and the differences in edge retention and performance relative to CRKs and Shiros "in the wild".
