Dr. Larrin Thomas, author of "Knife Engineering: Steel, Heat Treatment, and Geometry" has uploaded a new video. His website is www.knifesteelnerds.com
This video discusses balancing hardness, toughness, and edge retention with Magnacut, a knife steel he invented. However, the video also has charts with many other knife steel alloys:

He always has good info.
If you want another good reference (although not by Larrin), search either the Android or iOS App Store for "Knife Steel Composition Chart".
