I have several, depending on purpose, but one that exactly fits my hand is my Bark River Aurora. I did sand some spots down a bit to better fit me, but it came NIB feeling very good.
I also like my Horton Camp Blood, Helle Eggen and Mora #1 and have no complaints with their feel in-hand.
In Folders, I have noticed that Spydercos are generally very ergonomic.
