No law shall impose licensure, registration or special taxation on the ownership or possession of firearms or ammunition. Nor shall any law permit the confiscation of firearms, except those actually used in the commission of a felony.
Idaho Const. Art. I, § 11
Idaho law sets forth a clear rule that a person may carry concealed any knife with a blade that is four inches or less in length:
(2) As used in this chapter:
(a) “Concealed weapon” means any deadly weapon carried on or about the person in a manner not discernible by ordinary observation;
(b) “Deadly weapon” means:
(i) Any dirk, dirk knife, bowie knife, dagger or firearm;
(ii) Any other weapon, device, instrument, material or substance that is designed and manufactured to be readily capable of causing death or serious bodily injury; or
(iii) Any other weapon, device, instrument, material or substance that is intended by the person to be readily capable of causing death or serious bodily injury.

Idaho Code, 18-3302(2). (Emphasis added.)
To carry a knife, dirk, bowie knife or dagger with a larger blade, Idaho law provides that a person must possess a license to carry concealed weapons:
No person shall carry concealed weapons on or about his person without a license to carry concealed weapons, except:
(a) In the person’s place of abode or fixed place of business;
(b) On property in which the person has any ownership or leasehold interest;
(c) On private property where the person has permission to carry concealed weapons from any person with an ownership or leasehold interest;
(d) Outside the limits of or confines of any city, if the person is over eighteen (18) years of age and is not otherwise disqualified from being issued a license under subsection (11) of this section.
Idaho Code, 18-3302(3).
Notably, the statute does not prohibit the open carry of knives with blades that exceed four inches without a license. Idaho Code, 18-3302(4). Also, Idaho places no limitations on knives, cleavers or other instruments primarily used for food processing, preparation and/or consumption.
Avoid drinking alcohol while carrying a concealed knife in Idaho. State law provides that it is unlawful for any person to carry a concealed weapon on or about his person when intoxicated or under the influence of an intoxicating drink or drug.
