I have to say that I agree with Doc at least partly. I have never put a convex edge on a knife and I have flat sharpened evry convex one I have resharpened and some time that takes a LONG time on a stone. I have read tutorials on convexing with mouse pads and stuff but I have sharpened on a "stone" so long that anything else feels foreign to me.

I have to say though that what has affected me the most is that none of the convex edges I have had have been able to be touched up on my Sharpmaker. Maybe some of you guys can tell me if that is just because the convex is too thick or just because its convex. I really like my Sharpmaker for touch ups. In the field while hunting though I take a fine DMT.
