I participated in a similarly discussion some time ago on this forum, but am unable to find the link. If we are limiting the discussion to a general-purpose personal survival kit that can be brought on an aircraft as carry on I made the following observations. Looking at the current lists available at
www.tsa.gov the following are approved items; scissors -metal with pointed tips and blades shorter than four inches and up to four books of safety matches (non-strike anywhere) permitted as carry on but not checked. Taking the basic contents of my PSK and substituting scissors for a knife and replacing book matches for the Ritter Spark Light, which could be construed as a lighter, I should be good to go. HOWEVER, the TSA Security Checkers are not the sharpest spoons in the drawer and may view a PSK as SUSPICIOUS! I therefore carry these items scattered in my laptop/attaché case as to not draw undue attention. I curse al-Qaeda for the loss of my RIGHT to carry my pocketknife while traveling.
