I've never had a strider, but from what I understand, the tiger stripe is a fully DLC coated blade, and then media blasted away on the light parts, which make the stripes...that would lead me to believe it'd be more prone to rust.
I've heard the digicam coating is very tough, and should protect it well from rust.
However, I have no personal experience, so take that for what it's worth. Hopefully some others can give us personal experience.
