I have never had any questions about my spyderco enduras when I have traveled... germany, netherlands, france, italy, czech, poland, russia, switzerland & austria... never went to the isles, but I think they may freak there.... LOL I can also attest to never having been "picked up" in most of these counties by the athorities, other than routine (read drug search) stops. I have been picked up in Russia for "improper papers" (read bribe) but they didnt say a word about it.... I am sure they would have, if it were a big deal.... It might have gotten them more rubles LOL
PS, was never stopped from gettting on a flight with an endura, or the rescue that i carried for a few years, prior to 9/11 either....
