Flying commercial is one of those times when cheaper gear is better than the more expensive stuff. I try to only take things I wouldn't mind having stolen, by TSA or any other thief.

A Nuwaii QIII and a Spyderco Endura cost about $80, total. I may lose one or the other, but probably not both. Beats losing my HDS Ultimate 60 and Sebenza. <img src="/images/graemlins/smile.gif" alt="" />
