I've slowly been working the edge with a Falkniven 4 inch "diamond" sharpener.
Definitely getting better. A long process, as I am being very careful. I would not have attempted this if it was a convex edge.

I am looking into better sharpening options, and strops / compounds, and will do some more in depth searches in the forum. My search fu is horrible, but getting better. (I bought my first computer around 2008)

There is just something very nice about this knife. Feels good in the hand.
Pretty sure I'll get another one if some other things I"m working are successful. Will definitely get (2) 911s, and most likely 2 ea. of any more "11" series blades. This one just came out while I am trying to do some other near very expensive term projects with my funds.
