Query: Corkscrew is not well designed

I own another waiters corkscrew of another brand so I have a valid comparsion.First: the knife that is part of Pultap corkscrew just does not remove the foil very well from the top of the wine bottle. It is useless. I have to use a separate small knife for the job.Second: The screw part of the corkscrew is very difficult to remove from the recess in the handle. I have to use the same knife to extend it out that I used to remove the foil.Third:For some reason this corkscrew seems to break the cork during extraction leaving a piece in the neck.And finally, the double hinging does work but its usefullness is over-rated.
