a liner locks thickness isnt always a real good indicator of lock strength.
i have several EKI's and 2 emerson customs, through the yrs i have also had several MOD's, none of the MOD folders has really "grabbed" me, i do like the MOD razorback (even though its not full tang) for a FB, it comes with imho one of the best sheaths to come with a production FB, and while the folders are serviceable none has ever grabbed me like a CQC7, CQC8, SOCFK, P-Tac, or my CQC12, imho the '12 is wayy superior to any MOD folder in almost every respect (ie stronger lock, more secure in the hand handle, better blade shape, thinner, lighter, way more secure in the hand) so imho i would have to say i very much prefer EKI stuff to MOD stuff. and not just the '12, would have to say the same about the '8 and '7 too.
not that MOD is bad, i just have never really gotten into them, one thing i dont like about them is all the BS on the blade (ie design by massad ayoob/director/lethal force institute/every day carry razorback, just way too much info for me lol).
imho MOD is more of a utility knife vs an EKI being more a SD knife, to me anyway.
