Your sources are either mistaken or have a non-typical pricing scheme. My comment was based on empirical data gathered from keeping track of many, many thousands of dollars I've spent on steel purchased this year. Additionally, for every dollar I've spent, my friend that owns one of the biggest knifemaking supply houses (where I work in the AM a few days/week) in the world has spent 10. We get great prices because of our volume. XHP is consistently one of our most expensive alloys. I can go on and on about friends, acquaintances and business partners in the steel world, knife retail world and knife production world, etc,, but there is no need. The simple fact is that XHP is a great choice for knives in spite of its higher cost and lower name recognition. I often joke with other makers that I could sell twice as many knives and save production money if I would just start using S30V.
About the carbides: there is a lot more to edge retention than "wear resistance carbides". This statement is based again on empirical data, my own study and the tutelage of a friend that is a metallurgist (that specialized in stainless steel alloys).
