Personally, I love BG-42. I have a CR Sebenza in BG-42, and two Bucks in BG-42. I think that Paul Bos heat treats Bucks BG-42. All I can say is that Im blown away by the performance and stainlessness of Bucks BG-42 blades. They sharpen up better than any other stainless steel knives I have. Ive used the heck out of them, and havent had any chipping or premature dulling problems. Not a speck of rust either. And if you get a serrated BG-42 blade from PCKS
..Wow!!!! My serrated Buck110 in BG-42 cuts through anything I throw at it.
