Victorinox Classic SD in "Night Dive" coloration. I embraced the utility of the lowly Classic SD one year on vacation, when it was the only knife I carried all week. Like magic, it was the only knife I needed that week too. I still enjoy going to a 54mm Victorinox as my primary blade - often carried under the shirt with a AAA light on a neck lanyard.
I really like this surface - what is it?
