I'm a huge fan of the original Schempp Rock Salt; I've had mine since it was first released, going on 10 years now.
Truly an incredible design, one of the few credible 'do all knives.' Negative blade angle gives it a good amount of chopping power, while the refined ergonomics allow close up grips for doing precision cutting tasks. I think it's the coolest fixed blade Spyderco has ever produced.
That said, I've lately been thinking that I'd love to have a 'Rock Chopper' - a heavier version of the Rock, that's less 'do all knife' and more 'Mini Kukri.'
The current Rock/Rock Salt is 3mm thick, weighing 9.2oz.
I imagine the 'Rock Chopper' as pretty much the same knife, just 6mm thick, and without the weight reducing swedge at the tip. Everything else would remain the same.
Here's an crude 'paint' photoshop.
Basically the Rock, with a 6mm full thickness, Kukri like spine profile:
Does that interest anyone else?
