I had Newt make me a Uji without the lateral curve in the spine, hoping to make it a more generally useful utility blade. Only sorta worked, but that's what I get for trying to crowbar a fighting pattern into a kitchen knife. The expectations were wrong on my part. FWIW at about the same price as I paid for the Uji, the Executive NRGS neck knife I got from him is an amazingly handy utility knife.
The construction of the Uji I have is good for the price point. It may not win a beauty contest, but that's not what I buy Newt's blades for. On the Uji handle the micarta scales with grooves in them haven't slipped yet in my experience. But the lack of a guard always makes me a bit nervous about my fingers sliding up onto the blade. Like the other Livesay blades I own, this one seems to have a really hard edge. I think he's got his heat treat nailed down solid.
After considerable effort getting used to sharpening the chisel grind, it again has a sharp edge on it. It came sharp NIB, I messed the edge up trying to learn how to sharpen it, then finally got it back to somewhat sharp again. Not sure I like chisel grinds or if I'll get another one.
As Joebe mentioned above on his Woo sheath, the sheath on my Uji is also pretty tight. But that may be a necessary trait for a neck sheath that is holding a full-size blade inverted. If the stiff draw were a show-stopper for me, it could easily be remedied with a heat gun.
