Well, I don't know if it's the world's best cutter. It's straight-forward to use and a little unusual in appearance (which leads to comments during wine bottle opening ceremonies). My eleven-year-old son used it immediately out of the box with excellent results (and of course without reading the instructions). Clean cuts. A bit big for my aesthetic taste, but it does what it's supposed to do.My last foil cutter was simple to use and operate (coming with one of those elaborate opener fixtures), and the plastic disintegrated after only a year. This looks to be much sturdier. Time will tell.$9 isn't cheap, nor is it expensive -- I am satisfied.Postscript: It broke. I would say after about 20 or so bottles. The company immediately replaced it with a substitute -- not the same one. I noticed that it has been discontinued. It was still pretty cool and an attractive design. I would downgrade to 2 stars. Company service gets 5 stars.
