Well, fellas, I live in Texas and we can carry low-yield nukes provided they are in a porper suitcase container. Seriously, the way I read the law here, if the blade is less than 5.25", not a switchblade or a "dagger" (assuming they mean a two edge fixed blade) you can carry it.
But Ian you're right about the stigma of a karambit; there can be no confusing what it intended for. Could be a real liability problem if you had to gut someone in self-defense
