I have a yellow PE version that saw two years of continuous carry, before I went full-bore into slipjoints. Here are my thoughts:
At 3 oz, it is ridiculously light for its size. Its ergos are great, both handle and blade; it feels safe to choke up on the blade, and it uses the Endura 3 platform, if memory serves. It has not rusted in two years of sweat, water immersion, and general use, and will not because every bit and bob is FRN (fiberglass reinforced nylon...re: plastic), Ti, or H1.
H1 gets tougher with use, and I believe it. That said, I smurfed the angle when I first sharpened it, and it can be difficult to sharpen as time goes on, as the H1 gets harder. Granted, I was more of a sharpening novice then, and haven't attempted it again.
It's a great knife, and mine holds a special place in my heart, even though my cutlery tastes have changed. I also have a H1 Ladybug, Salt 1, Tasman (all yellow), and a black Saver Salt. I really like the concept of rust free knives.
Caveat emptor, if you get an early production Salt knife, the etched H1 may "bleed" a little rust. This isn't the H1, but leftover ferrous particulate matter from the laser etching process. Don't think this will be an issue on the black bladed PacSalts, since they are more recent.
