I've had a caly 3 CF for maybe 4 years now, and carried it but was never really happy with the cutting performance as far as sharpness is concerned. I recently got into stropping, so after a quick sharpening on the sharpmaker i stropped the edge which took off the burr, and holy crap it's sharp. It came from the factory with a somewhat blunt tip, so i fixed that as well. It's been in my pocket a week and its great. It bumped my lg seb 21 cf out for now.
