Kansas Knife Laws

Lawful with conditions · read 2026-09-04

Kansas permits most edged steel, but attaches conditions that catch buyers out. Ballistic knives barred; otherwise permissive with preemption.

Kansas sets no statewide blade-length ceiling on concealed carry. That does not mean any blade may be concealed — intent, pattern and place still govern, and a court will read all three.

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

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

Can this house ship steel to Kansas?

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.
