Missouri's CCW is a "Weapons" permit other wise I would not carry it. The max length with out the permit is 4". anything over is a felony. Most of the time I carry a Queen or a Schatt and Morgan slip joint and a Spyderco Military or Endura or a buck 110.

JYD#14 Do you need one, of course you do it's a knife and you like knives.....
