The newest iteration of Vanax is Vanax Superclean. Chad Kelly (xplorer42) and I are are working with Uddeholm right now helping to test the steel. We are using various heat treats in one of my fillet designs and are compiling the data for a report. There are two new test knives in transit to Costa Rica right now and we should know a lot more by the end of the month. Preliminary experience with the steel is positive. Here’s a link to some of the early testing on the Spyderco forum if you are interested. I will update once we have more info.
