This model features a very sharp cork screw, and two fulcrum points for particularly difficult corks. The knife blade is short, but sufficient for cutting wine bottle capsules, and what else would you need a knife blade for? It also has a hook for popping beer bottle caps, and even a tab at the end of the fulcrums for prying up pull tabs on cans.
This model was purchased from a large Asian market in Los Angeles
(San Gabriel) for 2020 US $2.89.
