double hinged wine key

Listings commonly show three foil-cutter styles: serrated cutters, flat-blade cutters, and extendable 4-wheel foil cutters.

Most use a five-turn worm; listings often describe it as a 5-turn non-stick worm or a 5-turn stainless-steel worm.

Available finishes include gunmetal black, classic black, matte black, slick white, and a fire-engine red all-over finish; some descriptions also note a soft-touch black coating.

They are manually powered. The double-hinged mechanism provides added leverage to make uncorking smoother and more efficient.

Common integrations include a foil cutter (serrated, flat, or 4-wheel), a built-in bottle opener, and a 5-turn screw/worm (often described as non-stick).

They are described as compact and travel-friendly; many listings show an overall length of about 4.75 inches and note they fit in pockets or drawers for travel, picnics, and everyday carry.

Weights reported range from 0.14 to 0.22 pounds, with several listings clustered around 0.14–0.16 pounds.

Descriptions mention comfortable, curved or ergonomic grips, and some models note a soft-touch coating for a pleasant feel.
