I glanced around BladeForums. The "Pirahna" brand was mentioned in a couple posts, and favorably both times.
If I were you, I'd sign up for BladeForums free Basic account, and go ask folks in their Switchblade forum.
EDIT: found a couple other positive posts on other forums, including several folks mentioning that these are built in Idaho, of all places. Not sure if all components are built in the U.S., or part outsourced, or what. Also note that
1sks sells the Pirahna line, and that's a pretty reputable online seller.
From 1sks:
PIRANHA AUTOMATIC KNIVES
Who says all cool knives have to be tactical?
A relatively new knife company, Piranha has been quitely producing fine automatics for 2 years. Like so many great automatic knife companies before them, the Pirahna Knife Co. began their life in a machine shop. Now they are using their precision machining knowledge and skills to produce high quality knives with a Sport Utility feel to them - strong enough to get the job done, but comfortable and pleasing to the eye.
I do like their "plum" metal finish. You don't see purple switchblades every day.
If you need a fallback plan, the Kershaw Chive (assisted-opening) knife is outstanding, and about $20. Gets rave reviews both here and BladeForum, pocket clip, stainless, lightning-fast, razor-sharp, etc.
