I do know from experience that P38 can openers are allowed. I carry 1 in my wallet and have not had any problems with the TSA!
If you don't have one, PM me and we will mail you some ASAP! I'll even tell why I keep so many on hand!
Wicked! That would be cool, wildman! Why so many????
I had one once upon a time, but I think backpackboy took it and ditched it when he got frustrated with it trying to open a can of beans. I haven't seen it since that trip. LOL! I loved that little thing! Mine had a little spoon thingy on the end, thought I thought was the bomb! I used mine to scrape tinder. Not entirely without frustration, but it worked!!
I think I'm going pick-up a cheap multi-tool when I land, and shore it up with a nice little folder or neck knife. I can mail them back home to myself when I'm done, or gift them to my older nephews.
