Canvassing opinions on Extreme Ratio fixed blades:

Are they any good? Are they worth the money?
This new proprietary steel N690- what would be its closet
counterpart? ATS-34? 440C?
Their blade profiles seem ‘over-designed’ is this just a ‘market branding’
device or is there real utility to these shapes?

Thanks
 
N690 is not a proprietary steel. Benchmade uses it in ther Red Class knives. Comperable to 440C. That's what their webpage says anyway.

they look kind of like the "dork ops" knives to me. I also dont like the lettering on the blades.

From what I gather, Dark Ops was founded by a forumer ER employee, and that the DO "designs", if not the actual knives themselves, are direct ripoffs of ERs.
 
N690 is an Austrian steel showing up in a few companies' knives now. Ontario just came out with a folder in it. I read that it resembles VG-10. These comparisons, of course, are only approximate -- or why have different steels anyway.

I haven't used their fixed blades but I own a Nemesis folder. The edge sharpens up nicely, even though the blade is extremely thick, and holds up well.
 
ER says there that N690 is a martensitic chromium stainless steel, with the following composition: Carbon 1.07, Chromium 17.00, Cobalt 1.50, Manganese 0.40, Molybdenum 1.10, Silicon 0.40 amd Vanadium 0.10. They state they do two heat treats and can put blades out at HRC 60 without being brittle. Their blades are marked HRC 58 so they must draw it back a few points. There was a test in a current German knife magazine, pressing on the point and the side of the blade with some sort of measuring device and the neither ER folder or the blade broke. Cannot read German so cannot be more specific.
