Texas law specifies daggers, dirks, poniards and Bowie knives as being illegal in addition to any knife with a blade greater than 5.5" being illegal.
There is no legal, re: Texas law, definition of a dagger, a dirk, a poniard or a Bowie knife. Using Webster, or any other dictionary, a dagger is described (paraphrasing here) as being a double edged knife with a symettrical or nearly symettrical, blade. A dirk is simply a "short" dagger. A poniard is just the French word for dagger.
So in essence, the Texas law makes illegal any dagger, short dagger or French dagger, along with Bowie knives.
There is Texas case law that defines blade length as the straight line measurement of a blade from the tip to the guard, or where the guard would be if said knife were to be madd with a guard.
There is also case law kinda defining what double edged means - any amount, as little as 1/2 inch, of the spine being "sharpened" as making a knife "double edged", with no definition of what "sharp" means. Don't you just love the way they write laws? And judicial opinions?
With respect to "Bowie knife definitions", there are none, but 1 judge is quoted (again paraphrasing), "I can't tell you what a Bowie knife is, but I know one when I see one."
Some LEOs go by the same justification - they know "one" when they see one, whatever the "one" may be at the time.
I've only had one LEO ask me specifically if the knife I was using at the time was a dagger. It was a symettrical spear point 5"blade. I had already used it and put it up by the time he asked, so I asked him if it was alright to go ahead and pull it out again (just to make sure I couldn't be tagged with "brandishing". He said, "Go ahead."
I pulled it out, held it up and said, "Yes, it is symettrical like a dagger, but a dagger is sharp on both sides." And commenced to beat the hell out of my forearm with the spine. And then I said, "See, not sharp. Not a dagger. Not gonna do that with the other side, though."
He just laughed and said "Yep, not a dagger."
Most Texas LEOs are cool about knives, unless you are being an idiot, already being looked at for some reason, etc. They don't carry rulers with them. The ones I've spoken to about measuring blades say they use a dollar bill, which is nearly 6" long. As long as the knife is less than a dollar bill long, they don't worry about it, again unless you are being a doofus or did something else criminal.
The only dickhead LEOs I have encountered have been not Texas natives. Not saying all nonTexas native Texas LEOs have a knife problem, but the ones that do, have brought their damnyankee attitudes with them from NY/NJ/CN/MA.
And yes, damnyankee is a word in Texas, and can be used as either a noun or an adjective.
