(a) No person shall knowingly carry or have concealed on his or her person or concealed ready at hand, any deadly weapon.
(b) This section does not apply to officers, agents or employees of this or any other state or the United States, or to law enforcement officers, authorized to carry concealed weapons or dangerous ordnance, and acting within the scope of their duties.
(c) It is an affirmative defense to a charge under this section of carrying or having control of a weapon other than dangerous ordnance, that the actor was not otherwise prohibited by law from having the weapon, and that any of the following applies:
(1) The weapon was carried or kept ready at hand by the actor for defensive purposes, while the actor was engaged in or was going to or from the actor's lawful business or occupation, which business or occupation was of such character or was necessarily carried on in such manner or at such a time or place as to render the actor particularly susceptible to criminal attack, such as would justify a prudent person in going armed.
(2) The weapon was carried or kept ready at hand by the actor for defensive purposes, while the actor was engaged in a lawful activity and had reasonable cause to fear a criminal attack upon the actor or a member of the actor's family, or upon the actor's home, such as would justify a prudent person in going armed.
(3) The weapon was carried or kept ready at hand by the actor for any lawful purpose and while in the actor's own home.
(4) The weapon was being transported in a motor vehicle for any lawful purpose, and was not on the actor's person, and, if the weapon was a firearm, was carried in compliance with the applicable requirements of Section 672.04(c).
(d) Whoever violates this section is guilty of carrying concealed weapons, a misdemeanor of the first degree, provided the offender has not previously been convicted of a violation of this section or of any offense of violence, and provided the weapon involved is not a firearm and the violation of this section is not committed at premises for which a D permit has been issued under Ohio R.C. Chapter 4303, and provided the weapon involved is not a firearm that is either loaded or for which the offender has ammunition ready at hand and provided the weapon involved is not dangerous ordnance, and provided the offense is not committed aboard an aircraft, or with purpose to carry a concealed weapon aboard an aircraft, regardless of the weapon involved. The penalty shall be as provided in Section 698.02.
