The
Leatherman Style PS is a small set of keychain pliers that came out in 2011 ans is still in production today. It came out as TSA compliant but depending on where you go and who the TSA personnel is you may get this item confiscated anyway so be careful. It is a very nice little set of pliers based on the
Skeletool frame. Although not a scissor based keychain multi-tool the PS also has a decent pair of small scissors included.
