Texas Law also makes it illegal to even posses a switchblade knife, defined as;
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.
If this is the case, why is it legal to sell butterfly knives in Mall shops?
