Newt's knives are really used by special forces and others who, unlike me, are much more than weekend backpackers. I'm a "simple is elegant" kind of guy though, and I love working with large knives on local brush. I've been playing with cheap machete's for a long time, but got a Livesay RCM about 3 months ago and used it extensively around here throughout the summer. I love it! I have an Air Assault as well, a great general purpose camp knife, and a small assortment of Newt's neck knives (a few of which he has sent me as thanks for buying his bigger knives).
I think Newt has been known to the special forces community for some time now (his half brother is (or was) in SF). I think he's just being discovered by the rest of the custom knife buying community and I'm very happy for him as he well deserves it. His knives are simple but well fitted and sold at useable prices... Just the sort of customs I go for!
