Delaware Code Title 11. Crimes and Criminal Procedure § 1446A. Undetectable knives; commercial manufacture for commercial sale offers for commercial sale; or possession

(a) Any person in this state who commercially manufactures or causes to be commercially manufactured, or who knowingly imports into the state for commercial sale, keeps for commercial sale, or offers or exposes for commercial sale, or who possesses any undetectable knife is guilty of a class G felony. As used in this section, an “undetectable knife” means any knife or other instrument with or without a handguard that is capable of ready use as a stabbing weapon that may inflict serious physical injury or death that is commercially manufactured to be used as a weapon and is not detectable by a metal detector or magnetometer because there is no material permanently affixed that would be detectable by a metal detector or magnetometer, either handheld or otherwise, that is set at standard calibration.

(b) Notwithstanding any other provision of law, all knives or other instruments with or without a handguard that are capable of ready use as a stabbing weapon that may inflict serious physical injury or death that are commercially manufactured in this state that utilize materials that are not detectable by a metal detector or magnetometer, shall be manufactured to include permanently installed materials that will ensure they are detectable by a metal detector or magnetometer, either handheld or otherwise, that is set at standard calibration.

(c) This section shall not apply to the manufacture or importation of undetectable knives for sale to a law-enforcement or military entity nor shall this section apply to the subsequent sale of these knives to law enforcement or military entity.

(d) This section shall not apply to the manufacture or importation of undetectable knives for sale to federal, state, and local historical societies, museums, and institutional collections which are open to the public, provided that the undetectable knives are properly housed and secured from unauthorized handling, nor shall this section apply to the subsequent sale of the knives to these societies, museums, and collections.
