Laguiole champagne knives is a good sample. They can impress all of you when you invite some friends to your place to celebrate some anniversary or festivals. This ritual legend comes from the victory of the ancient European battle group when the victor used a saber to cut off the champagne corks during the celebration. The waiter (ceremonial officer) wore a gown, with one hand holding the bottom of the champagne bottle, the other holding the champagne knife/champagne cutter and chopping off the stopper in the direction of the cork. As the stopper flew out, champagne rose like a stream of water, and everyone stood and applauded.
