I like the 0560 / 0561. I carry them when I cannot pocket my XMs. 0550 sometimes too.

Like when in route to the airport.

They stay in the vehicle, but in my checked luggage is a Cryo (photoed earlier in this thread) and a Benchmade mini grip or a Spyderco Delica w/ Emerson wave. Depending on where I'm headed I pack accordingly. All my travel knives are small though, to avoid size issues in many places.

I don't bring my XMs when I fly because I don't trust them to always be in my luggage when I retrieve it. Only thing keeping anything I check as mine is a TSA lock and hope for honesty and respect from my fellow human.
