Imagine a CPM10V blade edge with S7 on the outside. Check out the stats on this graph. The 10V and the S7 are almost polar opposite of each other.

It almost seems that 10V and S7 are meant to be laminated together.
10V and S7 are both amazing in their own way. But, although combining them may sound like the perfect recipe for "ULTRA" steel. It may not be as great as you would assume.
Consider: that if you wanted the S7 on the outside for "toughness" - I assume you might be wanting to chop with it or similar, but you would still have chips on the 10V edge to contend with - and a steel that is VERY hard to sharpen at the core and with chips.
And there wouldn't be much to gain by adding S7 to a non-abuse slicer.
The two steels are too extreme and would cost to much to combine for just a mid-size casual user.
But, maybe I am missing something?
