I've had this discussion with Doug, the guys at our Bear Quest, and all the guides at the Solana Hunt...where they skin more deer and hogs in a year than any of us would shoot in a life time! It's not how sharp an edge should be but what type of edge holds up best.
Previously, I would get my edge scary sharp to a mirror polish. That edge seems to dull quicker than one that has a slight burr. I now sharpen to a fine diamond stone on my Gatco system instead of going to extra fine-ceramic-leather.
I'd be interested to hear other opinions...Doc
