This subsection shall not apply to carrying a machete on one’s person or in a vehicle if the machete is carried for the purpose of cutting vegetation or if the machete is being transported for the purpose of cutting vegetation. In a prosecution of a violation of this subsection, there shall be a permissible inference that such carrying of a machete is not for the purposes of cutting vegetation. Such presumption may be rebutted.
