Abstract
A manually operated corkscrew is disclosed with a substantially U-shaped body having first and second ends. A rack with teeth is moveable within the body. The rack has first and second ends and is biased to move toward the second end of the body. Two symmetrical wings are provided on the second end of the rack with an extension spike mounted therebetween. A handle, pivotally attached at a pivot to the body adjacent to the first end of the body also has an axis joint disposed adjacent to the pivot. A ratchet claw, with a claw end, is pivotally disposed on the axis joint and biased so that the claw end engages the teeth on the rack. The handle acts as a first-class lever when activated about the pivot to gradually push the rack toward the first end of the body through progressive engagement between the ratchet claw and the teeth on the rack.
