Question about the opening tab of CS Golden Eye

[POCEH KOCEB]

Gentlemen, quick question about the way the opening tab of CS Golden Eye is fixed to the blade:
Is this internal hex screw and if it is, does anyone have idea about the size of it on Golden Eye and the Khan ?
I did take few pix with microscope and I believe it is not a roll pin or rivet, it looks like an internal hex screw, just curious about the size of it on those two knives. Thank you in advance.

On my Grik, a 0.035" wrench worked, which is approx 0.9mm

You mean, you were able to remove it ? Can you confirm that this is indeed a internal hex screw please ?

Never mind man, I found your post in the "Grik!" thread with pictures, thanks !

Yes I was able to remove it (the screw) and the thumb ramp. If you look at the "Grik!" thread, I posted a pic of the removed ramp, with the screw still on the end of the wrench. The Khan is probably similar, but not sure about the Golden Eye or their other higher end models with the thumb ramp.
