Iowa Knife Laws

Lawful with conditions · read 2026-09-04

Iowa permits most edged steel, but attaches conditions that catch buyers out. Concealed blades over 5in are treated as dangerous weapons.

Concealed carry in Iowa is capped at 5 inches of blade. A blade over that ceiling carried out of sight is an offence regardless of why it was carried.

Open carry carries no statewide length ceiling in Iowa. Sheathed, visible and plainly for work or display is the safest posture anywhere in the union.

Iowa does not preempt local ordinance. Cities and counties may — and do — write stricter law than the capital, so the town you are standing in matters as much as the state.

Your town may be stricter

Iowa permits local ordinance, and this house holds no reading for any particular town here. The state stands as written above; your city may not. Read your own municipal code before you carry.

Can this house ship steel to Iowa?

Shipping is possession, not carry — most provinces permit ownership of what they forbid on the street. Warborn Blades ships to buyers of age in the United States and Canada, and the counter refuses a barred road before a card is ever touched.
