when i first saw it i thought it was an S4 as well but messer corrected me.he told me what all three of them where called but i forget.i know the one on the far left is definitely not the S6 as thats been out forever and was the first scrapyard knife ever.

i wouldnt buy the one that looks like the S4 simply because its so similar to my MPLE.i'm sure what i will do when the other ones come out,if they come out because as of now they are just prototypes.

of coarse if i have extra money just lying around than whet the hell ya know but right now things are tight and its only what i really,really want.

as far as the DM and YK i dont even compare them because i think they are so different.

people dont get what the CGDM's .285 thickness is for.i think its obvious.its for prying open doors in iraq and compton.if you want a cutter get the YK although the DM cuts fine imo.
