Here is an example of two old school CQC-6 folders.
While made in the same era there are many differences.
One is a left hand grind, one is a right hand grind.

First a basic photo of both knives. Notice the "correct grind"
CQC-6 has the clip on the same side as the logo. This is
a rarity even among halfmoon sixes.





Now on to the backspacers.... the correct grind six has a micarta
spacer while the other has a Titanium back spacer. The TI backspacer
is also very rare.




The knife with the right hand grind has serrations on the top scale
and the left hand ground does not. Also look at the difference between
the cutouts for the thumb disk slot. Also a huge difference is the top
swedge on the two different knives.





Look at the difference in the blade tips. The one with the left hand grind
is much wider than the one with the right hand grind.




Look at the deeper scallop on the scale on the left hand grind
compared to the scallop on the right hand grind.





And lastly, what surprised me the most is the thickness of the blade steel.
I really don't know how best to measure the thickness but my calipers show the thickness of the
left hand ground blade is 1.28 and the thickness of the right hand blade is somewhat thinner at 1.12.
