Needed a smaller EDC than I normally prefer (so as not to offend our security sheeple) for opening cases at work and settled on a Dragonfly 2 in ZDP-189. I'll admit I've never been a huge fan of the humpback and Spyderhole, but beauty is as beauty does and I'm "warming" to this knife every time I use it. I typically do not reprofile factory grind angles and assume this steel could be a bear. I do most of my sharpening on a Lansky and I've got every diamond and conventional stone they make right down to the sapphire, although I swear the white stone is finer (although that may come from the considerable mileage I've got on it). If I want to just maintain the factory edge, what angle does Spyderco use?
