Champagne Sabre - $150
But HOW does one sabre a bottle? Glad you asked.
Step 1: Aim the blade toward the top lip of the bottle, and run it along the vertical seam, where the glass is weakest.
Step 2: Strike in an upward motion away from the base of the bottle like the badass medieval knight/mercenary warrior you are.
Step 3: Champagne shower. (Pop pop pop pop it in tha club.)
Protip: While champagne is this sabre's target of choice, a tool this good can give even sparkling apple juice a Napoleon complex. Use it on every bubbly beverage in a glass bottle you can get your hands on. But remember, with great power comes great responsibility. Sabre safely and (mostly) soberly.
