District of Columbia Knife Laws

Strictly governed · read 2026-09-04

District of Columbia governs edged steel closely, and more than one common pattern is barred outright. Blades over 3in are restricted; automatics barred.

Concealed carry in District of Columbia is capped at 3 inches of blade. A blade over that ceiling carried out of sight is an offence regardless of why it was carried.

Open carry in District of Columbia is capped at 3 inches of blade.

District of Columbia preempts local ordinance. One rule governs the whole province, and a city may not write a stricter one.

Can this house ship steel to District of Columbia?

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.
