I carried a Keltec P-380 and a 4” knife everyday for my entire career at the power plant that had a no weapon policy. Small pocket holster prevented printing in jeans while the knife was considered a work device as we were issued electricians knives that got thrown into a drawer. Never got close to needing either, but it was a comfort knowing I could defend myself if hiding or running was out of the question which should be the first course of getting away from a workplace shooting.
