Out-the-front (OTF) knives, a type of automatic or switchblade knife, have grown in popularity among knife enthusiasts due to their unique design and quick deployment mechanism. If you live in or plan to visit Indiana and are wondering about the legality of carrying an OTF knife, this comprehensive guide will provide you with detailed information about Indiana's knife laws, especially concerning OTF knives. We will also explore the types of knives allowed and prohibited, where you can carry them, and important considerations for responsible ownership.

An OTF (Out-The-Front) knife is a type of automatic knife where the blade deploys straight out of the front of the handle by pressing a button or sliding a switch. Unlike folding knives, OTF knives do not fold but retract the blade back into the handle when not in use. These knives are also known as switchblades or telescoping knives.
OTF knives use a spring-loaded mechanism inside the handle. When the slider or button is activated, tension in the spring releases, propelling the blade out rapidly. Double-action OTF knives allow the blade to both extend and retract automatically with the switch. The blade locks securely when open and closed to ensure safe handling.
*Visual demonstrations* of the internal mechanism and operation of OTF knives can be found in various detailed videos that show disassembly and function, illustrating the spring, detents, and locking mechanisms working in milliseconds for quick deployment and retraction.
Indiana is known for having relatively lenient knife laws compared to many other states in the U.S. The state permits the ownership and carry of a wide variety of knives, including automatic knives like OTF knives, with some specific restrictions.
- Ownership: OTF knives, classified as a type of switchblade or automatic knife, are legal to own in Indiana. The ban on switchblades was lifted in 2013, making automatic knives fully legal for possession and sale in the state.
- Carry: You can legally carry OTF knives both openly and concealed in Indiana without special permits or restrictions at the state level.
- Blade Length: Indiana does not impose any blade length restrictions on knives, including OTF knives.
- Prohibited Knives: The only knives explicitly prohibited are ballistic knives (knives with detachable blades propelled by a mechanism) and Chinese throwing stars (shuriken with multiple blades set at different angles).
- No Statewide Concealment Restrictions: Indiana does not restrict the concealed carry of knives, including OTF knives.
- No Blade Length Limits: You can carry knives of any blade length legally.
- School Property: It is illegal to possess knives on school property if intended to be used as a weapon.
- Local Ordinances: Some cities or counties may have additional restrictions, such as prohibiting knives in public parks or government buildings.
- Statewide Preemption: Indiana has statewide preemption for knife laws, meaning state law generally overrides local ordinances, but some local restrictions may still apply.
- OTF knives (automatic switchblades)
- Balisongs (butterfly knives)
- Bowie knives and large fixed blades
- Assisted-opening knives
- Dirks, daggers, and other stabbing knives
- Single-blade throwing knives
- Disguised knives
- Ballistic knives (knives with blades that can be ejected by gas, spring, or other mechanisms)
- Chinese throwing stars (multi-bladed throwing weapons)

Indiana law restricts knife possession primarily in the following places:
- School property: Carrying knives intended as weapons is prohibited.
- School buses and special purpose buses: Knives are banned.
- Airports: Knives are generally prohibited inside airport terminals.
- Certain local government buildings: Some courthouses and civic centers restrict knives.
- Public parks in some cities: For example, South Bend prohibits carrying knives in public parks.
Outside these restricted areas, carrying an OTF knife openly or concealed is generally legal throughout Indiana.
- Intent matters: Carrying a knife with the intent to use it as a weapon can lead to criminal charges.
- Felons: Felons face additional restrictions, especially on school property.
- Providing knives to intoxicated persons: Illegal to provide deadly weapons, including knives, to intoxicated individuals.
- Local laws: Always check local ordinances as some cities may have additional rules.
