I don't understand. If a dagger is illegal, in your state, you're not going to find a legal dagger. A dagger, by definition, has two edges. That's that :-( did you mean you're trying to find a knife that looks just like a dagger, but is actually single edged? As far as "how serious" well... look at it like this - find out if it's a felony or a misdemeanor. If it's a misdemeanor, getting caught with it wouldn't be a life crushing experience, but (on top of everythingelse) you'd lose the knife. That would prolly pale compared to the grand or two in fines and cost of probation, but u could still own guns (after probation), vote, etc. Now, if its a felony, very big deal. Also, even of it's a misdemeanor, it could swing a jury around in what would've been a justified self defense case to you being a predator armed with an illegal weapon. Just food for thought.
