This is a quote from the municipal code:
Sec. 21-17. Certain knives prohibited generally; exceptions; penalty for violation.
(a) It shall be unlawful for any person to intentionally or knowingly carry on or about his person a knife with a blade less than five and one-half (5 1/2) inches in length, which knife is equipped with a lock mechanism so that upon opening, it becomes a fixed blade knife.
(b) The above prohibition set forth in subsection (a) shall not be applicable to a person carrying such a knife:

(5) Using such a knife in connection with a lawful occupation, during such utilization.
(Code 1959, § 26-28.1)
Pathetic isn't it?! It's hard to believe that this town exists in Texas. (A wonderful state.)
