With a man like Sal Glesser behind the helm I am proud to own and carry Spydercos.
I did make the mistake of taking my Caly3 to the beach once, and it resulted in a pretty gritty action. I had to rinse out the knife a couple times to restore it back to its incredible smoothness. I found the more open design of the Para-Military to be much easier to clean out debris when facing the same conditions (sandy beach). I think that the lack of openness is the lockback's only real con in daily usage.
