I took a chance on this 3 knife lot for $13 shipped... it looks like I might have gotten some 84mm scissors but not sure. The 2 larger knives seem to be the same size. One of them doesn't have back tools, so it has to be 84mm...plus looking down at the scissors joint, it looks like my other 2 84mm scissors.
I checked on an older 91mm with squared phillips and the scissors joint doesn't look like this.
No pics of the tools deployed unfortunately. Here's the seller's pics:
