BenjaboolyThis has a spine flipper tab, so I'm not sure what you mean. If you're referring to the framelock, then it will never be 'lefty friendly' because it would have to be a 'lefty version' of the design entirely.
CyphreNone of their nicer knives have a reversable clip. i can use a frame lock fine with my left hand, but i dont want to have to switch hands after putting it out of my pocket
