From a "fit and finish" standpoint I think they're lovely (they are Seki-made, right?) They have nice grinds, an attractive shape, and a good overall finish. I've seen some rough surfaces in the hard-to-reach areas, but that's natural. They're very slim and I think you'll find they feel and look smaller than you might expect from the dimesnsions.
My gripe is with the lock. I've handled several A.G. Russell one-handers and a Crawford of similar design, and on all I found the lock stiff and difficult. The slim handle offers little purchase and the lock requires enough force that when it does release it can be a bit startling and I've seen many folks nearly get cut. I eventually learned how to close them one-handed, but I never felt safe doing it and I decidedly don't like it, even with two hands. It's secure and workable, but I can't imagine being able to close it with the unconscious ease that midlocks, linerlocks, and the Axis-lock allow after only a little practice.
In short, nice knives, but if you have another choice with a more conventional lock, I'd take that.
