If you work in a facility that prohibits "weapons" you might want to familiarize yourself self with the legal definition of that word in Texas. TGT member matefrio fought the good fight on that issue.I work in Healthcare and our hospital has a pretty strict "no concealed firearm" policy on campus, not sure about the vehicle. I like the ability to pay my mortgage and bills so just follow their rules. We can, however, carry knives, so people may not be able to shoot you down a hospital corridor, but hand-to-hand combat is not prohibited! That being said, not sure what they would say about a back mounted machete :-)
IIRC, a small pocket knife is not a weapon, a machete is a weapon, and the possession of an LTC and a firearm bears authoritatively on whether or not you can legally carry such a weapon.
But don't trust my faulty memory.
