Coop has a good point, seems like most serrated H1 models have a bit of PE at the tip.
Which means the SE blades are really CE blades, but with hardly any PE. Okay, I know, that's stretching it, but I think Coop has a good point.
I only have one SE Salt series knife (the Aqua Salt), but that's beginning to sell me on SE knives in general. I may need to pick up an SE Pacific Salt and try that for EDC. Up till now I have to say I haven't had much use for SE or CE blades, but that's frankly been an unwarranted prejudice. My SE Aqua Salt does not have the drawbacks I thought it would, just takes some getting used to. Still, I'm not completely sold yet. What I am sold on is the Spyderco Spyderedge, I think the Spyderco serration design is superior to most others. And I'm not a scientist, but I've heard (and believe) that serration design is critical, and ranks right up there with steel type.
