Here's the law:
(6) “Illegal Knife” means a:
(A) knife with a blade over five and one half inches;
Rainer v. State, 763 S.W.2d 615 (Tex. App.-Eastland 1989, pet. ref’d) To determine
length, measure entire length of blade past handle, not just the sharpened portion of the
blade. Same result in McMurrough v. State, 995 S.W.2d 944 (Tex. App.-Ft. Worth 1999).
(B) hand instrument designed to cut or stab another by being thrown;
Albert v. State, 659 S.W.2d 41 (Tex. App.-Houston [14th Dist.] 1983, pet. ref’d) Martial
arts throwing star qualifies as “a hand instrument designed to cut or stab another by being
thrown”.
(C) dagger including but not limited to a dirk, stiletto, and poniard;
Armendariz v. State, 396 S.W.2d 132 (Tex. Crim. App. 1965) A knife slightly over seven
inches in length when open, equipped with a double guard, blade that locks open and is
sharpened on both sides of blade for over an inch meets the definition of a dagger.
(D) bowie knife;
Mireles v. State, 192 S.W. 241 (Tex. Crim. App. 1917) A knife in a scabbard with a blade
nine inches long and a handle four or five inches long described as a butcher knife was
embraced in the term “bowie knife” as defined by the Penal Code.
(E) sword; or
(F) spear.
(7) “Knife” means any bladed hand instrument that is capable of inflicting serious
bodily injury or death by cutting or stabbing a person with the instrument.
(11) “Switchblade knife” means any knife that has a blade that folds, closes, or
retracts into the handle or sheath, and that:
(A) opens automatically by pressure applied to a button or other device
located on the handle; or

gravity or by the application of centrifugal force.
This definition includes a “butterfly knife”.

I've always thought the switch blade/gravity restriction was complete bull. I can get my perfectly legal spyderco out and into action faster than any hood can get their switchblade out. It's a law based COMPLETELY on perception and not reality.
