"oops."
I "think" I
may have "fixed" it.

Took it apart to clean & lube ... and to c if the bearings would fit the M21-02G (nope.

)
When I reassembled I put the pivot pin in with flat pointing forward. Liner lock would not catch/engage at all.
Took apart a second time, positioned the flat facing rear.
Looks to me the lock bar is fully engaged now.

I musta screwed up somehow ...
NEW QUESTION:
As far as I know, the knife is
not a clone.
(would a clone have the ball bearing pivots, or use bushings? my guess is bushings, sinc cheaper and easier to get - or make.)
The knife is a CRKT LCK+. Quality is at least as good as the CRKT Ken Onion 'RIPPLE' I bought at a brick n morter knife shop back in 2013 or 2014.
With the blade centered, and no wigglie-wobblies when open partially or fully, it can be flicked fully open without using the tab, tip facing rear in a normal grip, or tip facing front, in a reverse grip.
Is it "normal" for the LCK+ to be flickable?
Being flickable is legal in Idaho, so I am not concerned about legalities.
