Well said, all. I now carry either a free-standing set of SAK scissors from a swisscard, or a set on emt shears, which seem to escape criticism and still cut things, as well as a mini-bic lighter in carry-on. Have added a poncho liner and collapsible rei walking stick to accommodate some age related napping and mobility needs. Synthetic underwear fan, too, like Blast, tho I am stunned to hear that he wears underwear at all-RPI grads of my acquaintance generally did not-or if they did, it was something in leather or latex.
