OBG, we sailed on Carnival Cruise and we did have to go thru a metal detecter and out belongings were sent thru an x-ray machine. Or should I say our carry on things, I have no idea what protocalls were in place for our "checked" luggage. I took my keychain that had my SAK and gerber infinity on it out of my pocket, right in front of one of their screeners and placed it in the tray to go thru the x-ray. He didn't say anything, no alarms went off as it went thru.....
Picked it up when it came out the other side and headed into the terminal.
I was very happy, and releived. As a creature of habit I haven't been without a pocket knife since about the 3rd grade. Back then it was a Schrade three bladed pen knife. By the time I hit 6th it was a SAK, scout model. Although I carry a 4" folder now for self defence as well as heavy chore cutting at the plant and don't like to be without one, without a simple SAK I feel naked, like a fish outta water. Just can't do it without the fact that I have nothing to cut with gnawing at my brain......
