Another new guy from Oklahoma here too, Guthrie OK.
I have found that, for me, it really depends on the knife, what it will be used for, and what type of edge I want. Monday, I spent 3 hours on a santoku, re-profiling it and then getting it to almost mirror. I spent an hour yesterday sharpening a santoku for my son. For a folder that I want a really nice mirror on it can take a few sessions over a few days for around 6-8 hours at the most. For a simple touch up where I am matching the bevel, 20 -30 minutes is reasonable for me.
