I've been through four (yes, four) Davidoff cutters in the last three months. Seems they've changed to a different manufacturer and they're having all sorts of problems with the quality and alignment of the blades. Specifically, when the blades are sliding past one another they 'catch' and you get a pair of dings on each blade about a half inch apart. I should've taken pictures....
Once they've got the dings they don't close all the way. Which of course means they can't cut a cigar all the way through.
The problem has been escalated to Geneva (according to the local rep). Needless to say, I'm a little dissapointed.
I have five Xicars (one in my suitcase, one that I carry, one on loan to a friend who's having the same problem with his Davidoff cutter, one in the Montegue next to my chair, and a spare in my closet). It's not as nice a cut as that made by the Davidoff, but at least it works.
If the one that you're considering has been sitting on the B&M's shelf for at least a year it should be the original (good) production. I'd stay away from the new production.
