Large blades, swords, daggers etc are now legal to carry in Texas if you have a concealed handgun license.
Since I believe in vigorously exercising freedoms (use it or lose it!), I picked up a dagger: A Boker made Applegate Fairbairn dagger.
It came with a new fangled Tek Lok attachment system for the kydex sheath, and it made it very easy to mount it to my shoulder holster rig in the inverted position. Just in time for the cold months too.
Anyways, an outstanding fighting knife - very light in hand, blade just a hair under 6", and excellent balance so lightning quick. Highly recommended.
