Pocket knives are popular everyday carry items in Iowa, but state laws impose clear limits on concealed carry based on blade length and type.
Iowa defines “dangerous weapons” to include knives with blades over five inches, affecting how you can legally transport them. Understanding these rules helps avoid misdemeanor charges.
Iowa’s Definition of Dangerous Weapons
Iowa Code Section 702.7 labels a knife as a “dangerous weapon” if it has a blade exceeding five inches, or if it is a dagger, razor, stiletto, or switchblade designed to inflict serious harm.
Pocket knives under that length typically do not qualify unless they fit those prohibited categories. This distinction drives most carry restrictions.
Open Carry Rules
Open carry of pocket knives is generally legal statewide in Iowa, as long as the knife is not a prohibited offensive weapon and remains plainly visible.
No statewide preemption exists, so local ordinances in cities like Des Moines or Cedar Rapids might add rules—always check municipal codes. Folding pocket knives stay compliant when clipped visibly on a pocket or belt.
Concealed Carry Restrictions
Concealed carry gets stricter under Iowa Code 724.4: blades over eight inches concealed (without using in a crime) is an aggravated misdemeanor, while five to eight inches is a serious misdemeanor.
Blades five inches or shorter can be concealed legally, provided they are not dangerous weapons like switchblades. Permits are not required for standard pocket knives but are needed for larger or restricted types.
Exceptions apply for lawful activities, such as hunting or fishing with a valid license, or carrying in your own home or business.
Prohibited Places and Situations
Schools, airports, courthouses, and government buildings ban knives entirely as weapons-free zones.
Private property owners can prohibit knives, and carrying while intoxicated escalates penalties. Minors face extra hurdles; those under 21 need permits for certain knives over five inches.
Penalties for Violations
Violating concealed carry rules often results in fines from $315 to $6,250 and up to two years in jail, depending on blade length and circumstances.
Possession of offensive weapons like ballistic knives can lead to felony charges with longer sentences. Recent preemption enhancements (HF 2556) protect against conflicting local laws, allowing damages for violations.
Key Advice for Iowa Knife Owners
Stick to blades five inches or shorter for concealed carry to stay safe, and opt for open carry when possible. Verify local rules and avoid restricted areas. For the latest, consult Iowa Code directly or a local attorney, as laws can evolve.
