Tom Mayo is VERY right about the stuff work hardening. As mentioned above, I have only worked with Cruwear, not Vascowear, but the two are essentially the same steel. If you do work with it, be sure that you use the old "grind then dunk" method. I work with it without gloves so I am able to tell pretty quickly when it is time dunk it water. It does take a bit longer to make a knife with this stuff but in my opinion, it is worth it. Just don't get it hot!
My experience with Cruwear is that it holds an edge forever. I have some CPM 3V that I am getting ready to grind and I will be able to do a fairly good comparison between the two.
Texas Knifemakers Supply in Houston Texas still carries Cruwear and provide a heat treat service for it as well.
