Grayman Knives' Dua folding blade.
I've been carrying one of Grayman Knives' smaller offerings, the Dua ($255), for several months now, and have found that it's really growing on me. With a thick three inch blade, this little guy is just as rugged as the larger offerings from Grayman that I've reviewed such as the Dinka and the Sub-Saharan. In the beginning, I found that the knife sticks a little, making it difficult to lock and unlock the blade one handed. However, as I broke the knife in a little, this stickiness went away after a week or two.

You might also notice that the top of the blade and handle has two teeth in it, useful to help you get a good grip on the Dua while doing some heavy cutting. Despite being a folder, I found that the Dua, like previous Grayman knives, is built for ruggedness rather than finesse.
Since my auto-assist Benchmade didn't survive the first time I left it in my pants and my wife put it through the wash, I've been rocking the Dua ever since. Tell you the truth, I don't see any need to replace it with any other knife.
