As someone who stares at key organizers enough to cause concern in my loved ones, I think I understand this situation.
So essentially there is a slight premium to pay on this drop for the new diamond coat.
This coat is claimed to be stronger than without it, thus the what looks like a 5 dollar increase for both models when compared to the standard models.
The "blackout edc" trend is picking up and keysmart wants them dollars too so here we are. I will say it looks pretty dang good though.
I have limited experience with the diamond black coating in the form of the pocket hanger clip, and I will say it is very resistant to scuffs, and feels good and smooth in the hand. I would say this drop is worth it, price wise it is not too much of a discount because it is the first run on a new product. I think we can say that by joining this drop we would not be paying the 5 dollar increase premium for the new coating overall.
