Steel is what they’re calling VG-Max= VG10 with more carbon added.Shun are excellent knives. However, steel choice should be 1st before brand. I personally do not like VG10. It is too hard, tends to get micro chips on the edge, especially if you use plastic or bamboo cutting boards or for boning meat. It really should only be used on hardwood blocks. Also when it comes to hardness, it holds an edge for a long time, but that also means it takes much more effort to restore an edge. Ceramic or stones really are the only things you should use on them, not a steel hone. That being said, if you are good about knife use and care, they will last you a long time.
