I got a 770 on trade a few weeks ago, and immediately noticed that when deassisted it... Was terrible. Kind of like my Buck Vantage Pro, no amount of pivot adjustment would make it flip well. It needed a hard wrist snap or the torsion bar to not suck. Off to Kershaw it went for repair because it seemed as if the detent didn't really exist, and was more of a suggestion than a feature. A somewhat long conversation with Kershaw ended with them saying it was perfectly within specs, and many of the 770s don't function well as a manual. I fully intended on trading the knife when I got it back today, but I figured I would give it one more shot.
When I got the torsion bar out, it was the same. Lots of wrist action needed. I remembered just then how the detent is not just dependent on the depth of the hole, but also pressure from the liner. It had to be the liner! I immediately noticed that the liner is full thickness throughout, not cutout to ease bending it. After a butt load of muscling and some really sore fingers, I significantly increased the liner bend, and it is now just a hair under touching the other scale (obviously the blade tang stops it, nice early lockup). Popped the knife back together and... We'll it isn't perfect, but now the wrist action needed is almost none, just the normal movement I have developed from having a lot of less than perfect knives.
Remember, if your flipper doesn't flip check the lock bar. You might just save yourself the few weeks I wasted on something this idiot should have thought of before he shipped off his knife, and way before he completely gave up on the knife.
Also thought I would add that a little heat shrink tubing on the clip makes it not leave the normal clip marks on the scales that are an eyesore. The more you know.
