Once went through CPH security with my daughter who had a whole arsenal of knitting needles with her. All fine, we even asked the friendly staff about it and were told knitting needles are allowed. She then forgot her phone there, which we then called and they were kind to answer it and tell us in which lane it was.
Once got caught in the domestic terminal there with a potato peeler in the pocket of my jacket. Had used it to peel carrots at lunch and had forgotten all about it. He confiscated it and told me that in the US I would have been detained for that. I said ok, took it away from him, walked back through the metal detector, out to my car where I deposited it and came back ! You should have seen the gaping look on his face. Hilarious ! Well, it had a slightly pointy tip, but I think the crew would have wet themselves from laughter if I had attempted a highjack using it.
