Ah! So they are made of dark matter! I want two!.Yes, but you need to check it in if you are flying...
Most folks seem unaware there is a model of the Swiss Army Knife that has a lens cap remover in it. There's a pincer device that folds out, slips down into the lens hood and pinches the cap off quicker than you can say Swiss Bank Account! I think the knife is the "Photographer" model -- less than $100.
Not so -- a feature of that particular model is that it can only be seen by photographers. At least that's what I've heard. I don't have one myself.
