In my opinion the opening and closing smoothness has more to do with those hard, smooth steel liners against the PB washers with the M-4 blade sandwiched in between.
I thought about that too. I have a couple folders from another maker that are not even remotely smooth. Not sure why the "other guys" haven't gotten up to date. I mean, nylon washers? Puhleez!
