Welcome to the forums

.
I think you'll find that the Dark Ops brand in general doesn't get too much respect in this community. Primarily, if not entirely because of their marketing. They have a reputation as a company that's giving the knife community an image of bloodthirsty killers, an image that a lot of the responsible knife users on this forum are constantly trying to fight in order to keep our privileges safe. They also don't look very appealing to many and don't seem practical for normal use.
However, from the little that I've read about the knives in general, they seem to be solid knives that can handle hard use. If you're interested in checking out similar knives that hold a lot more respect around these parts, may I suggest that you also look into Extrema Ratio?
Other names that I personally like:
Spyderco
Benchmade
Kershaw/ Zero Tolerance
SOG
Fallkniven
Busse
Chris Reeve
Swamp Rat
Ranger Knives
You might also want to look into Cold Steel and you should know that they are also highly controversial here as well, but they have solid designs in general.
