Sabrage is one of the few occasions nowadays where it is entirely acceptable to draw a sword at the dinner table. The technique is simple: a single firm stroke along the seam of the bottle towards the neck, and the cork disappears in a clean cut with a distinct pop. It looks dramatic. It is also quite straightforward once you've learned it. The most important thing is having the right tool.
This sabre from Pulltex has a handle in oak and is delivered in a wooden case. Made from stainless steel, 50.5 cm long. A top-class gift for those who appreciate both ceremony and champagne.
