knife with a corkscrew and lever (which doubles as crown cork opener) with either a knife or auto-foiler to remove the foil top of wine bottles and then the cork. Designed to be screwed in to within 1 full rotation before the end of the screw (more will pierce the bottom of the cork and result in extra flotsam on the surface of the wine) before levering out the cork. Mounted corkscrew This tool is used by businesses that need to open a large volume of wine efficiently and without waste or breakage. It is a large brass tubular device, fixed at a 45° angle to the bar, with a lever pivoted halfway and extending towards the user. The bottle's neck is inserted firmly in the lower aperture of the tube and the lever pulled down firmly and steadily to the bottom. This drives a corkscrew into the cork at a regular depth each time. When the lever is returned to its original position it extracts the cork. When the bottle is removed pull the lever to expose the cork at the bottom, it loosens the cork and returns the lever firmly to its starting position, whereupon the cork will then fall out. Twin prong cork puller The twin prong cork puller, also called the Butler's Friend or Ah-so, is shaped like a large key with a squared oval handle about 5 cm × 8 cm, and two thin metal strips, approximately 10 cm long, 5 mm wide, and 0.5 mm thick, descending in tandem from the center of the handle. The two strips are spread open and then wiggled into the space between the cork and the bottle on either side. Once fully in place, a turn and pull of the handle causes friction to turn the cork and pull it out of the bottle. Injuries New Zealand has had in average 40 injuries recorded by the Accident Compensation Corporation per year due to injuries while opening a beer bottle that required to remove a metal lid. Two ophthalmologists Cam Loveridge-Easther and Sacha Moore wrote a letter recommending for warnings to be put on bottles. References Bottles Food preparation utensils Domestic implements
