I believe the actual limit under Texas state law is 5.5 inches.

You might be interested in a Cold Steel Voyager extra large. Mine has blade of 5.3 inches.

I haven’t updated that list for over a decade, so YMMV.

You’re probably right - that’s what I get for trusting the top of my head. I actually carry a Boker Armed Forces, 3.25”, because that’s just under the limit in DC, where I pull reserve duty.
