Another thing, with San Antonio and Corpus Christi, it's a little foggy.
San Antonio bans locking folders. The balisong is kinda both. It folds and the blade is held firmly in place. When open it's almost like a hybrid locking folder fixed blade. Probably take a court case to clear that one up.
Corpus, with their ban on all fixed blades and a 3 inch limit on folders, presents a similar but different challenge. A 3 inch single edge balisong meets the length and folder specs, but since it functionally acts like a fixed blade when open, again we have limbo-land on how LEOs and judges will perceive it. Again, a court case will have to clear that up.
Now, if we end up getting a pre=emption bill passed in the Legislature this year (knock on wood). These issues will become moot. Here's hoping.
