Jim I've been EDCing one of my 2011 Sprint Run C-60 models with the G-10 handle/scales for at least 4 months now. And I've been totally blown away at how versatile the C-60 is for everyday chores. Previously I had been EDCing my M390 Military for over 4 and half years. No doubt that the M390 blade on the Military model is far superior to the VG-10 blade on my C-60 Ayoob. But the C-60 blade with the streamlined design is more versatile than the Military model.
Both knives are great Spyderco models for sure. But a C-60 Ayoob model with a premium supersteel blade might be one I could EDC for years under the right circumstances. Most people regard the C-60 as strictly a self defense blade>> but I'm here to tell everyone it's much more than that.
