so the way I read your post my Kershaw leek would be illegal in San Antonio because it has a liner lock?? the buck 110 would also not be allowed because of the lock it has??
Yes, Richard, that is correct. The state law max blade length limit for legal carry in public is 5.5". Texas has 2 levels of knife definitions - legal and illegal.
Legal means "legal to carry in public".
A Legal knife - max 5.5 inches as measured from hilt front to the tip of the knife, straight line (NOT along the edge), single edge. Effective 01 September 2013, any switchblade or balisong knife that meets the definition is legal 5.5 inch, single edge.
Illegal knife - basically anything that does not meet the definition of "legal knife". Also, specifically named in state law as being illegal are daggers, dirks, poniards, and bowie knives. Or as I like to put it, "daggers, short daggers, daggers and bowie knives", since a dirk is a "short dagger" and poniard is simply French for "dagger".
Nowhere are any of these terms defined. The double edge prohibition comes from the illegality of daggers. Sometimes as little as 1/4 inch of sharpening on the swedge is enough for some (not anywhere close to most) LEOs to call a particular knife a dagger.
Bowie knife? Who knows what could be called a Bowie knife. Rezin Bowie (Jim Bowie's brother) described the original Bowie knife as being a straight blade, 9.5 inches long, 1.5 inches wide, and guard less, similar to a large butcher knife. I've heard of otherwise legal knives being called Bowies simply because they had guards or a clip blade or both.
On private property (your home, farm, ranch, hunting lease, while fishing, etc) you strap on anything your heart desires and your back could handle.
What San Antonio has done is pass an ordinance that says it is a criminal offense (misdemeanor) to carry within the city limits any locking blade knife with a blade length LESS THAN 5.5 inches. Since there is no such thing as a blade EXACTLY 5.5 inches, all locking blade knives are banned. Not fixed blades, just locking folders. "They" (the city council and the police chief at the time) SAID they only want it because of gang activity (based on web archived news articles from then). Corpus Christi enacted their 3" limit on all folders and ban on all fixed blades for the same PC reasons.
I may be interpreting the ordinances incorrectly (I am NOT an attorney and never desired to be one of the bottom-feeding mud cats) the way the CC ordinance is written, you COULD be arrested for having a steak/paring knife in a park to cut up a hot dog, sausage, apple, butter your bread, whatever.
