Michael, you seem to really like this TnT hawkbill. It also seems that your only real problem with it is the minute possibility that one day you are going to encounter an LEO and further, somehow get busted for possession of a dangerous weapon.
I think fishface5 pointed it out in the other thread - most, if not all, of the case law I've seen in the states that I've researched deals with things like (a) someone brought a knife to school, and raised as their defense that the knife was not a deadly weapon under the definition provided by the statutes, or (b) a person, while engaged in a criminal act, used or was caught with a knife and was trying to beat the deadly weapon charge by claiming the again that the knife was not a deadly weapon under the definition provided. The point is that you are a lawful citizen, not going to bring your knife to a courthouse, airport, federal building, etc. and therefore, this is not likely ever going to be an issue for you.
Now if you were carrying a Rekat Sifu, well then...

But don't sweat this one dude!
My opinion is that we are facing the very real prospect that one day in the future we will not be able to legally carry sharp tools of any kind. So for now, carry what you want, within reason, and be smart about it! That TnT hawkbill looks very nice - carry it!
