Does anyone have any experience with both of these metals? Whats the difference between the 2, performance-wise? Edge holding, etc.
 
N690 is essentially a modification of N695 (440C) with added cobalt. The cobalt increases the potential hardness and a couple other things.

It has a touch of Vanadium as well. Enough to act as a grain refiner.

You can download a full data sheet from the link above, but here is the synopsis from that page:
Martensitic chromium steel with cobalt, molybdenum and vanadium addition. For tools and components which can be hardened to very high hardness levels. Surface finish required for good corrosion resistance: fine ground or polished.

Composition:
C______1.07
Si______0.4
Mn_____0.4
Cr_____17.
Mo_____1.1
V______ 0.1
Co_____1.5
I prefer N690 to 440C. (And I count myself a fan of 440C. )
I found N690 to take a wicked sharp edge, the equal of what I get with VG10.
I find that edge retention rivals that of 154CM and VG10.

N695 is straight 440C
 
N695 has Added Copper and N690 has Cobalt.....properties and all temperature, density stuff are almost equal, so is the hardness. If you want more data see Bohler-Uddelholm website and download datasheet of both alloys.
