That carbon fiber is really something! It looks very high tech.
I succumbed not long ago and got a used Dua, and liked it so much that I caved and just got a Satu! The Dua needed a little tlc but now it is in great shape, the new Satu arrived perfect from Grayman. I think they must have perfected their build quality because mine has excellent fit and finish; even grind lines, totally solid lockup and perfectly centered. I got the all Titanium model, I really like it, and the handle has a beadblasted finish on it that gives good traction even if it is wet. They arrive now with a smooth convexed edge unless you request the "toothy" edge, mine would shave out of the bag (no it doesn't come with a box!) For such a tank of a knife it actually handles really well, the balance is perfect and it is "only" 5 and 5/8 long when closed, big but not totally insane. For edc certainly the dua makes more sense, but if you need a fixed blade but have to carry a folder the satu is a good choice. Thanks for all your info on these knives Striderco, I would not have found them otherwise.
