A bluddy
great big thumbs up to ITCZ.
I got pinged with my Leatherman at a regional airport screening point yesterday, despite not being questioned about it the previous two security screenings at Captal City airport screening points.
Showed the appropriate pages re tools of trade, from the link provided by ITCZ, and hey presto, Leatherman and I make it though unscathed and unseparated.
