Glad Texas isn't a nanny state.
HB 1935 became effective September 1, 2017 and made it so that there are no restrictions on the blade length of carry of knives in Texas except for location restrictions on knives with blades over 5-1/2 inches.
Knives with blades over 5-1/2 inches are defined as “location-restricted knives” and are not be able to be carried in establishments that receive more than 51% of their revenue from alcoholic sales, high school, college or professional sporting events, correctional facilities, medical facilities, amusement parks, or places of religious worship. There is an exception for someone using a location-restricted knife in a historical demonstration or ceremony in which the knife is significant to the performance of the ceremony.
HB 1935 also removed Bowie knives, daggers, dirks, stilletos, poniards, swords, and spears from the Texas statute 46.02 Unlawful Carrying Weapons and the definition of an illegal knife.
Great while you're in Texas but if you travel out of state it would be good to know the laws in each state you travel through. I make it a point to do so.
