Like all of Ernie's designs, the design is decent, the blade shapes have average usability, the ergonomics are pretty well thought out, the material choice is meh and the build quality is... okay. I know it's not a custom, but lets be honest, the reason you're buying the knife is because it says "Emerson design" on the side.
Frankly I think that the Kershaw versions are better made than their US counterparts, and that's pretty sad. The detents actually work on them, that's a plus, but I find them to be much tighter and less smooth on the draw. They also tend to have later lockups, which isn't a problem, it's just something to be aware of. Sharpening job can be sketchy, out of the two dozen or so I've handled a third of them had badly folded edges.
Overall, like I said, I've handled about two dozen of them. I make knives for a living, so it takes a lot to impress me. For the money, they're okay, but nothing really special. If that's all I had money for I'd take a look at them and compare them to other knives at the price point... then I would save my money a bit longer and buy something like a Kershaw Blur or a Benchmade 55X or 94X series knife, maybe a Spyderco PM2 if I could find one.
