Leaving from Geneva, I remembered after security that I didn't had any gifts...

Amongst the usual chocolates, I found the perfect gift: a Swiss knife that I proudly bought.

Few minutes later I realized... How is that possible? The blade doesn't exceed the palm of my hand but this is still a brand new sharp knife.

Does that mean that I will be allowed to carry this knife in my hand luggage through this airport security? What about others?
