Thom, sorry this isn't about the blade steel, but after living with the 3D Native for awhile, I prefer the older "flat Native." Just feels better to me, and I like the older blade shape a bit more. As for the wire clip, it ain't too bad, actually. I had had worries I wouldn't like it, but it's okay.
I have the following Natives:
-GIN 1 Native SE
-440V Native PE
-440V Blue G10 Native PE
-AUS-10 SS Native PE (2, one engraved)
-VG-10 Native III PE (Blue Spyderco Forum Model #040)
-440A BRK Native (okay, some of you don't think this one counts!)
My next Native will probably be the S30V model "flat" Native, or, if I scrape up the $$, one of the shell inlay models.
Unless an "MBC" or "large Native" comes out, that is! HINT, HINT...
