I do own both, and I wish I could help you more. I honestly never really used the CoS much. I ordered the coated blade, then when I got it I didn't really care for the looks of it. I'm crazy like that. You probable will be happy either way. The F1 is a really great design, it get's so many things right. It's really close to the perfect small do it all knife.Could you compare the VG7 to the CoS in your experience. You said you own both, no?
