Tennessee Knife Law Snapshot
Short version: Tennessee is generally favorable for ordinary knife carry after removal of its old switchblade and four-inch restrictions, but carrying weapons with intent to go armed, school property, and local/place restrictions still matter.
No current statewide four-inch knife cap found in reviewed sources.
Older summaries may mention repealed restrictions.
Weapons on school property are restricted.
Tennessee has broad local weapons preemption that includes knives.

Preemption and School Rules
Place-based and local rules are where many EDC mistakes happen. Check the exact school, courthouse, airport, park, transit system, workplace, venue, and private-property rule before carrying.
| Rule area | What to know | Status | Source |
|---|---|---|---|
| State preemption | Local governments generally cannot regulate knives more restrictively. | Caution | TCA section 39-17-1314 |
| School property | School restriction remains a major exception to normal EDC analysis. | Caution | TCA section 39-17-1309 |
Practical EDC Checklist
-
01Start with knife type: Confirm whether the knife is ordinary utility carry or a listed/restricted weapon category.
-
02Check carry method: Open carry and concealed carry can be treated differently.
-
03Check the place: Schools, courthouses, airports, jails, public buildings, parks, and private venues often have stricter rules.
-
04Check age and status: Minors, prohibited persons, and restricted-license contexts can change the answer.
-
05Avoid weapon-like conduct: Threatening display, unlawful intent, or criminal-use facts can turn a tool into a legal problem.
