Upon reflection(i.e. reading more carefully), I was thinking about pointy things in carry-on to include fish hooks and safety pins; flammable and incendiary for checked baggage: matches (all types), spark-lites, etc. Curiously, small lighters such as BICs seem to be ok "on your person". I understand that it's not vital to have a carry-on PSK on commercial flights and I do ship my gear/tools ahead of time to the installation sites and my PSK goes with it, but it's somewhat annoying that I can't just carry it on. FWIW
