This compact Brucart Corkscrew Deluxe Pack is a unique extracting system. Place the unit over the bottle. Turn the entire unit clockwise to insert into the cork. The axis in the center rises to act as an indicator to tell you when the cork is fully inserted. Pull the 2-1/2" lever arm away from the body to activate an eleven-step ratchet and spring loaded arm to extract the cork. Works similar to a carjack. Teflon coated spiral, stainless steel blade.
