I open the box, remove the knife, open it, check the lockup, check the edge, check the grind, set the knife down, grab the Allen wrench, disassemble the knife, and put it back together with the screw heads on the clip side.
I've never been able to figure it out. The small plain I have now is my third Sebenza, and I've handled a couple dozen more. They've all had great grinds, good to excellent factory edges, and perfect lockup. Fit and finish is impeccable. Obviously there's a lot of thought and care that goes into producing them. They're the finest production folders on the planet, maybe the best made folders, period-BUT somehow someone always manages to put the screws in backwards. The clip screw is always on the proper side. How the others all get put in facing the opposite direction, I don't know...
