IIRC, there was a discussion about S30V rusting more quickly, possibly due to certain types of bead-blast processing. I have no experience whatsoever with Strider knives, but I noticed my T1 Harsey with a bead-blast S30V blade seemed to rust MUCH easier than any of my other S30V knives.
That being said, is it possible that differences in manufacturing between runs could make some Strider knives more prone to rust?
Where do you live, roughly?
I've had rust problems with D2 blades that I EDC a lot. Never had a problem with S30V. Not just Strider blades but Sebenzas and others.
Thanks,
Rich
