PDK 25,
It's kind of a moot point. You should re-sharpen after every shot no matter what you use. SS doesn't oxidize as quick as carbon but, BHs should be touched up from time to time anyway. After any BH has been sharpened, keeping it that way is pretty simple. Touch it up on a stone, file, ceramic or leather. Whatever your preferred method is. My self, I like carbon. Easier to sharpen & easier to touch up & defiantly as sharp as SS. Besides that, it cost less. One benefit of SS is if you hunt in a lot of rain. Doesn't oxidize like carbon will.
