High-quality corkscrews feature hollow helical wire worms
Helical spiral steel wire cores into natural bottle corks without crumbling bark
Traditional corkscrews use a spiralled metal wire called a worm. Unlike a solid wood screw, a high-quality corkscrew worm is hollow down its central axis, allowing the steel helix to core into natural cork without expanding it or stripping inner bark fibres as it pulls upwards.
