This is a moment where CRK has to take a humble "cap in hand" and apologize for a failure of communication between our technical side and our customer service side. Yes, around mid-2013, the RC hardness on all the folding knives (Damascus excluded) was changed from 58-59 to 59-60. Our guarantee cards, brochure and website did not reflect that change. We are not happy about this lack of communication and are in the process of updating the relative published material.
Chris made the decision after reviewing the performance of S35VN at both hardnesses. He has always been a proponent of a slightly lower HRC to ensure shock absorbency and ease of sharpening. When he was convinced that blades at 59-60 would perform extremely well and meet all of his criteria, the change was gradually implemented. Bear in mind this is a possible spread of only 3% and a likely change of only 1% in the hardness and not a major change at all.
