I also really like my Salt I, but, that said, it is more for the blade steel than the specific design of the knife. Sure, it is lightweight and ergonomic, but in typical Spyderco fashion, the knife is far wider than it needs to be when closed, the tip is too blunt/rounded for my tastes, and the lockback isn't really my favorite.
I frankly don't understand why H1 hasn't been adopted into both more Spyderco designs and by other knife manufacturers in general. I'd love to see a nice lean Titanium framelock based knife with more of a spear or warncliff point and an H1 blade. How about some waved H1 knives, Spyderco? Why doesn't Benchmade come out with some H1 designs? I'd love an H1/waterproofed version of my EDC 530- already has an almost all polymer handle- just needs a water resistant Arc lock, an H1 blade and it's good to go.
