CPM154 and 154CM are not the Same Steel.
The CPM version is finer Grained and has it's carbides more evenly disbursed in the Blade making it hold it's edge longer and making it tougher than the 154CM.
I agree that there are a good number of Stainless Steels out there right now and Mission is in a position to choose the right one.
Mission also has a number of Friends in the Industry that would be more than willing to help.
This new Model seems to have a lot going for it from a use standpoint.
Recurve Blades cut very well.
I would be interested in more folks reaction to the design.
