and the real answer is you
risk your freedom and life if you unwisely cause fear or attract attention with that knife. It is possible to cause fear and/or attract the attention of LEO's without knowingly violating a law.
One may in fact become arrested wrongly, in violation of law, with all potential risks attached to such arrest, by visibly carrying weapons or claimed-to-be weapons around those of nervous disposition.
CYA first, THEN decide *IF* carrying a fixed blade knife is in your intersts.
In my own opinion attracting attention from nervous people is unwise.
