when you say razor sharp, is this literally, or just a euphemism for very sharp? IE, can you easily shave your arm hair?
I have a Lansky system and it does a nice job, but its not "razor sharp" even when I spend lots of time on it. Its very sharp, but not able to shave my arm.
This is on two Spyderco blades mainly with VG10 steel. I use it on other things too, kitchen stuff, and other guys blades.
