|  | AN ACT | 
|  | relating to the definition of a switchblade knife for purposes of | 
|  | the offense of prohibited weapons. | 
|  | BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF TEXAS: | 
|  | SECTION 1.  Section 46.01(11), Penal Code, is amended to | 
|  | read as follows: | 
|  | (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 | 
|  | [ (B)]  opens or releases a blade from the handle | 
|  | or sheath by the force of gravity or by the application of | 
|  | centrifugal force.  The term does not include a knife that has a | 
|  | spring, detent, or other mechanism designed to create a bias toward | 
|  | closure and that requires exertion applied to the blade by hand, | 
|  | wrist, or arm to overcome the bias toward closure and open the | 
|  | knife. | 
|  | SECTION 2.  The change in law made by this Act applies only | 
|  | to an offense committed on or after the effective date of this Act. | 
|  | An offense committed before the effective date of this Act is | 
|  | covered by the law in effect when the offense was committed, and the | 
|  | former law is continued in effect for that purpose.  For purposes of | 
|  | this section, an offense was committed before the effective date of | 
|  | this Act if any element of the offense was committed before that | 
|  | date. | 
|  | SECTION 3.  This Act takes effect September 1, 2009. |
