hello all. Just the other day i bought a spyderco military. It is absolutely a fantastic knife, but i want to get the absolute most out of it that is possible. I have the s30v model, and i feel like the factory edge is a little obtuse for ideal cutting. So my question to the sharpening guru's here is, how far do you think i can back spyderco's s30v down and prevent chipping and other such catastrophic failures of the edge? similarly, how fine a grit can i go with s30v? (this is my second s30v knife, and the first one im going to heavily modify the edge angle of). any thoughts, opinions, advice, or warnings would be much appreciated.
