so which one is what? the cg is saber grind? which knife would be heavier the cg or le?

You're correct. The CG has the saber grind and the LE has the full flat grind. The CG will be heavier than the LE because the grind angle of the CG is slightly more obtuse, and the CG blade has more full thickness than the LE. I hope that makes sense!
