I'm gonna be that pain-in-the-butt who doesn' answer the stated question.
Firstly, knife laws in NJ are supposed to be pretty draconian. Check 'em out before carrying anything, and never tell an officer you're carrying for any defense-related purpose. It's for picking your toenails or something...
Secondly, the strength advantages of an American tanto are widely exaggerated and you have little need of them in a folder, anyhow. I think you'd be better off going with a knife that had a standard drop-point or clip-point so you'd have some belly for slicing and a thinned blade profile and better tip for thrusting. I'm thinking AFCK, Genesis, Axis..
Thirdly, if defense is your goal, I'd recommend a Civilian head-and-shoulders over anything else out there. It was specifically designed to inflict substantial damage, even through heavy clothing, with a strike to nearly any area. It hits as hard as a folder can and gives you the chance to exit - a truly defensive weapon.
OK, dismounting soapbox...
