I have a Nomad. It's a great 3" blade. Like you would expect from Al Mar, the F&F is top-notch and the blade is as sharp as any production knife I've handled... equal to Spyderco's OOB sharpness, IMAO. The flat ground blade slices *very* well.
The liner lock is solid and mine hasn't moved in the year or so that I've had it. I don't EDC it, so it doesn't get that kind of use, but it has been carried and used. There is no noticable blade play in any direction, the liners and scales are very well mated and finished. The knife is light (probably why I don't carry it much), even with the SS liners, and the G10 is nice and grippy w/o being hard to pull from your pocket. The clip doesn't make the knife ride as low as the SERE & mini-SERE, but it's not bad.
They're a bit pricey, but that's an Al Mar characteristic. I think you do get a very good product for the $.
