No.
But in the real world, legal folder in a grammar school/high school is a big deal, but same at a college/university, meh, unless you did something perceived as a threat.
A fixed blade on your belt or just seeing that Safekeeper (which may not be legal in TN period) for example, could be perceived as threat in and of themselves. Perception is paramount.
I carried pocket knives all the years I worked at UTK, and saw many in the hands of maintenance guys, puter network guys, etc. Never thought anything about it, and didn't even know there was a law against it.
I dare say lots of folks carry pocket knives on college campuses and don't think anything about it, and don't even know the TN statute against it.
Note that this is not an encouragement on my part for anyone to break any law.
As the law stands, to be 100% sure you could never be charged under 39-17-1309, you shouldn't carry even a tiny Swiss Army on your key ring.
