I heard that they are a brand in name only.
Have seen some pretty awful reviews on them from gents who tried and did not like them a few years ago.
I got some this spring or summer and liked them quite a bit. Sharp, smooth, and consistent.
I would speculate that they have farmed out to a much better production facility than whomever made them in the past.
If it's true that they are made by a third party then the consistency of their quality and performance would be a legitimate question.
No one really knows for sure that I have seen.
My experience, recently, has been very positive.
Everything regarding the origination of the blades themselves I've seen in the last year has been pure speculation though.
I wouldn't go out of my way to get some or pay a premium for them right now. I wouldn't avoid them like the plague either.
I got mine from the website in Switzerland. Fair price and great service. I got 40 blades if I remember correctly. Got a bunch of Kai at the same time. The Bolzanos I have from that order are great. Have used a couple 5 packs without issue.
