Hi. I'm trying to get some info on this knife. http://www.phantomknives.com/ I've searched the forums and the web and there doesn't seem to be a lot of info from users/owners. Anyone own/handled/seen one of these? Impressions? I like the potential for fast opening, doesn't require a lot of "fine" motor skills, could hang somewhat inconspicuously from a belt. I'm concerned about the lock up. Bottom line questions: Does it work reliably? Is it rugged? Or is it just one of thoses "gimmicks" that sound great in a description but just don't hold up in actual use? Thanks for your help.
