Dark Ops are a joke around here because of their way-over-the-top marketing, styling, and because their designs were ripped off from Extrema Ratio.
As for the actual knives, I really don't know. Some reports are that they're solid as bricks, others have serious QC issues. Self-promoted hype aside, they're intended as hard use knives for "tactical" situations. Whatever the hell that means. What do you want the knife for? If it's for covertly deanimating cardboard boxes or whittling, it's way too much of a knife. The blade is definitely not designed for slicing, or anything utility, really. And they make no illusions otherwise. The knife was designed to stab people again and again. Their knives are marketed towards "operators", which means the vast majority of the people who buy their knives are the mall ninja/armchair commando type.
If I were you, I'd see about canceling the order, or returning it if it's too late. If you just want a big, tough knife (for the same price or less), look into a Spyderco Manix or Benchmade Rukus, and Kershaw's Zero Tolerance line. If you want to spend more, look at Striders.
