Notes: Other cutting instruments include scissors, hatchets, swords, sabers, meat cleavers, ice axes, and picks. Effective Dec. 22, 2005, scissors less than 4 inches and tools less than 7 inches were no longer prohibited.

Knives include any length and type except round-bladed, butter, and plastic cutlery.

Clubs includes martial arts items, baseball bats, night sticks, hammers, pool cues, and billy clubs.

Firearms includes any weapon (including a starter gun) that is designed to or may readily be converted to expel a projectile by the action of an explosive, as well as spear guns, BB guns, flare pistols, compressed air guns, and stunning devices.

Other refers to tools, self-defense items, compressed gas cylinders, bleach, lighters, and certain sporting goods. The jump in the number of other prohibited items in 2005 is a result of the inclusion of lighters as prohibited items as of Apr. 14, 2005. Lighters (except for torch lighters and micro torches) were removed from the prohibited items list effective Aug. 4, 2007.
