The offending article was an expensive and rather shiny Zippo lighter .....that ......had already passed through airport screening three times, including the one presently being described, but that ..... had never been an issue for concern
You could cut nose to spite face and have the security wally disciplined for allowing through DGs. Zippo lighters have a flammable liquid reservoir containing unabsorbed liquid fuel which I believe IATA DG regs prohibit on person or in baggage.
Could be wrong, though, maybe it's changed; DGs refreshers generally good time to catch up on sleep......
